Re: Return value from sub does not work in Aftergrasp(?)

Feel kind of stupid, could have tried out myself. Just never thought of using functions...certainly completely forgot about the update.txt...Thanks for your reply.

@0 isn't supported for most cases (supporting it resulting in the
creating of an @0 variable after every subroutine, and every command
which really put a drag on the execution speed).

In your example you'd want to write:

result = test_sub()
textln "returned is:"
text @result
wait
exitnow

test_sub:
local tmp_string "bye bye"
return @tmp_string

The trick to find this out was to to search for @0 in the UPDATE.TXT
log, you will find this from July 2003:

Added New command, INPUTBOX, puts up a very simple EXCEL style dialog
to enter a single text field.

RESULT = INPUTBOX(VARIABLE)
RESULT = INPUTBOX(VARIABLE,PROMPT)
RESULT = INPUTBOX(VARIABLE,PROMPT,TITLE)
INPUTBOX VARIABLE
INPUTBOX VARIABLE,PROMPT
INPUTBOX VARIABLE,PROMPT,TITLE

The return value is either "ok" or "cancel"

Use of @0 is also supported for the return value (like the messagebox
command). Remember @0 is generally NOT support in AfterGRASP, it's only
provided with a few commands (like MESSAGEBOX) to simplify coding and
supporting older scripts.

Nothing big and public. Mostly quiet projects.
