Code: Select all

```
logmode l
subroutine a(scalar !sum)
!sum = 0
for !k= 1 to 10 '!k is used for a different purpose in a than in b
!sum = !sum + !k
next
endsub
subroutine b
!k= 1
!sum = 0
call a(!sum)
logmsg k={!k} sum={!sum} 'Will display 10 instead of 1 for !k
endsub
call b
```

Specifically what I would like to see is a syntax like the following to be able to declare some program vars as being local to their subroutine:

Code: Select all

```
logmode l
subroutine a(scalar !sum)
local !k ' <===== LOCAL PROGRAM VAR DECLARATION HERE THAT WON'T REFERENCE THE GLOBAL VARIABLE DEFINED IN b
!sum = 0
for !k = 1 to 10
!sum = !sum + !k
next
endsub
subroutine b
!k= 1
!sum = 0
call a(!sum)
logmsg k={!k} sum={!sum} 'Will display 10 instead of 1 for !k
endsub
call b
```

Would something like this be possible? I would imagine that it's non-trivial because it requires keep a local variable stack for each subroutine invocation.
