Thanks for your work. AFAIK the last official F80 release was version 3.44 dated 10-Dec-81. Seems unlikely MS would still been involved with CP/M in 1985.

Have you tried linking the 3.44 libraries with code generated by v3.4. It is possible that the bug lies in the libraries.
As to the TRS-80 version, it may be the same core compiler with modified I/O routines to adapt it to run on the TRS80 and some minor changes to emit z80 code names.

Based on date, it is most likely that a CP/M version was made from the TRS-80 version.

I don't have the TRS-80 version but the dates looks plausible. It needs to be tested whether it has the bug.

The second one looks suspicious from the outset. I can't imagine MS bungling the copyright and creation dates.

Possibly Disassembled FORTRAN-80 Ver. 3.4 Copyright 1978, 79, 80 (C) By Microsoft Created: 19-Feb-85 was adapted for CP/M from it.

If someone has the opportunity to test the work of this compiler on TRS-80 or in the emulator, please do so.

To do this, compile the following small program and execute it.

type V2.for

C 234567
DIMENSION K(5)
DO 10 I=1,3
K(I)=100+I
10 CONTINUE
WRITE(1,100) K(1),K(2),K(3),K(4),K(5)

END

V2 (compiled with F80 v3.44 "Created: 10-Dec-81")

*** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** writes the value expected BUT puts it into the WRONG slot!

Please report the results. If there is no error in the TRS-80 version, then I will compare these programs and look for an error in the CP/M version.

Have you tried linking the 3.44 libraries with code generated by v3.4. It is possible that the bug lies in the libraries.
As to the TRS-80 version, it may be the same core compiler with modified I/O routines to adapt it to run on the TRS80 and some minor changes to emit z80 code names.

The error is in the compiler.
When compiling with the listing option, there is a string that is different from the listing generated by the correct compiler. I used the library from the compiler kit with an error.

Based on date, it is most likely that a CP/M version was made from the TRS-80 version.

I have versions 3.36, 3.4 and 3.44 for CP/M all copyrighted from 1978. The TRS80 was only delivered in Nov 1977, and CP/M was well established by then. This would suggest that the CP/M version was probably the original version.

On a separate note, was the TRS80 version for its own DOS or for its version of CP/M, which loaded programs higher in memory. I am aware that the Basic compiler had a version for the TRS80 version of CP/M, so the Fortran compiler may be similar.

Checking the 3.33, 3.36, 3.4 and 3.44 compilers on CP/M.
The error you highlight was only present in the 3.4 version.

What is interesting is that the 3.4 version uses Z80 mnemonics whilst the other versions use the intel ones. This suggests that Microsoft offered 8080 and z80 versions of the compiler. It is not clear whether the code generated or libraries were
optimised for the z80.

Have you tried linking the 3.44 libraries with code generated by v3.4. It is possible that the bug lies in the libraries.
As to the TRS-80 version, it may be the same core compiler with modified I/O routines to adapt it to run on the TRS80 and some minor changes to emit z80 code names.

The error is in the compiler.
When compiling with the listing option, there is a string that is different from the listing generated by the correct compiler. I used the library from the compiler kit with an error.

Based on date, it is most likely that a CP/M version was made from the TRS-80 version.

Andrey

Andrey
I have versions 3.36, 3.4 and 3.44 for CP/M all copyrighted from 1978. The TRS80 was only delivered in Nov 1977, and CP/M was well established by then. This would suggest that the CP/M version was probably the original version.

On a separate note, was the TRS80 version for its own DOS or for its version of CP/M, which loaded programs higher in memory. I am aware that the Basic compiler had a version for the TRS80 version of CP/M, so the Fortran compiler may be similar.
Mark

Andrey
I just looked at the distributed cpmio.mac source that came with F80 v3.44 and it clearly suggests the TRS80 version was probably for it's version of CP/M.
The top of the file is
TITLE CPMIO CONSOLE I/O ROUTINES FOR CP/M

Mark

Checking the 3.33, 3.36, 3.4 and 3.44 compilers on CP/M.
The error you highlight was only present in the 3.4 version.

What is interesting is that the 3.4 version uses Z80 mnemonics whilst the other versions use the intel ones. This suggests that Microsoft offered 8080 and z80 versions of the compiler. It is not clear whether the code generated or libraries were

optimised for the z80.

Mark

I think that only a new executable file was made for TRS 80. Most likely, the libraries were not changed, since the compiler generates i8080 commands and changes the mnemonics to z80 only in the listing.

I assume that for CP/M the FORTRAN compiler is 80 Ver. 3.4 Copyright 1978, 79, 80 (C) Microsoft Created: 19-Feb-85 was remade from the executable code of the FORTRAN-80 Ver compiler. 3.4 Copyright 1978, 79, 80 (C) Microsoft Created: 01-Dec-80 for TRS-80.

It is most likely that the original compiler for TRS-80 was prepared directly by Microsoft. Disassembly of the source file F80.CMD showed the presence in the executable file of a set of traps placed by the authors of the program to complicate its
disassembly. Fragments of superfluous code were excluded from the program modified for CP/M and a number of other actions were performed to overcome the protection against disassembly. A mistake was made in some place.

Who performed this transformation will remain unknown.

However, I disassembled the compiler F80 Ver. 3.44 for CP/M. The file with the program has the name F.MAC. Compiling this file results in the creation of an executable file completely identical to the original program.

Microsoft put hooks into many of their tools that check for an Apple 2

Microsoft released the FORTRAN compiler for CP/M and made releases with a binding to work in the TRS-80 and Apple 2 SoftCard environments. Perhaps even for some environments. The Microsoft manual even mentions Intel's ISIS II operating system. But I have
not found any implementations for ISIS II.

I found several implementations of the F80 compiler on the Internet.
There is version 3.4 for TRS-80 and "Apple 2 SoftCard". Both version in the listing generate Z80 mnemonics and both do not work under CP/M control.

The implementation for Apple 2 SoftCard should be closest to the version for CP/M. In this version, need to disable hardware binding.

Only managers who worked at the company at that time know how Microsoft licensed its products.

A license to work on another operating system clearly had a much higher cost. In this regard, third-party manufacturers could not purchase all the released versions for financial reasons. In addition, Microsoft maintained its priority in this matter.

Looking at MBASIC version '5.29' again, the characters representing copyright symbol in the sign-on was changed from (C) to a single byte $A4. It turns out the Amstrad CPC code to display the copyright symbol is $A4. Coincidentally
if run on a terminal that strips bit 7 it becomes $24 which is the ascii code for '$'.

Due to my preference for Z80 mnemonics, I chose an unsuccessful version of the executable file with an error to disassemble the Microsoft F80 compiler, then disassembled the latest version of this compiler with Intel mnemonics. It doesn't seem to have
errors. However, my interest in this compiler has not disappeared. From various Internet sources, I received several more executable files for different operating systems.
At this stage, I was able to establish that Microsoft was selling its compiler under its own name and as an OEM product for other systems. The compiler core remained unchanged, but various tricks were added to the program text to complicate disassembly.
Perhaps other developers were provided with parts of the compiler in object code format with instructions on how to use them to obtain an executable file for a particular system. I have collected several compilers of version 3.4. Apparently this is one
of the versions that was intended for use on third-party equipment. In the initial versions, there was no possibility of using included files. In the latest versions, it appeared, but was added in a hurry. Some of the routines are made in the form of
stubs. The processing functions of included files are most developed in the compiler version for the Z80 board on Apple computers. The advent of 16-bit processors stopped the further development of this compiler. Restoring the source code reminds me of
excavating cities of ancient civilizations. We find ancient and useless shards now and try to understand how people used to live and think. You have to spend a lot of effort on this activity, manually move tons of soil to get a result. But if this is not
done, it will not be possible to preserve the history of the development of our civilization.
