CALLBYNAME()

ok# = CALLBYNAME( sub_name$ )



This command allows to call a subroutine via the name as a string. If you don't see the advantage of this, switch to using GOSUB instead!

The return value is either TRUE or FALSE, indicating whether the subroutine exists or not.

ok = CALLBYNAME("mysub")

SUB mysub:
   PRINT "Hello", 0,0
   SHOWSCREEN
   MOUSEWAIT
ENDSUB



GLBasic calls a set of subroutines with this if they exist:

GLB_ON_QUIT


shortly before the program quits. Just close your files and RETURN as soon as possible.

GLB_WIN32_MSG


If a windows message is avaliable. Read it with PeekMessage (... PM_NOREMOVE).
