A possibile bug but only when there is []IO=1
program print, and only when there is ")box on"
APL NARS2000 (Win64) Version # 0.5.14.11
)box on
Was OFF

here repeat the linke cancel the first 2 chars of above "[]<-"

this below when box is off... all ok
)box off
Was ON
{a<- 1 2 <> []<-'[]IO=',[]IO <> a[2]}
1 2
[]IO= 1
2
In pratice
when []IO is 1 and )box is on
{[]<-a<- 1 2 <> []<-'[]IO =',[]IO <> a[2]}
this above print that []IO is 0, and 2 is out of index of "a"
but if change line above remove "[]<-"
{a<- 1 2 <> []<-'[]IO =',[]IO <> a[2]}
this above print that []IO is 1, and 2 is out of index of a
when []IO is 1 and )box is off
{[]<-a<- 1 2 <> []<-'[]IO =',[]IO <> a[2]}
print 1 2
print []IO is 1
print a[2]
so all ok
