Title: strange
Post by: Peter on August 31, 2011, 11:20:57 AM

Hi Charles,

This is a bit strange.

InitSound: sys_mode=4
with this position you cannot hear the sound!
This will not initialised.

If you jump out of an 'elseif' into a  'Sub' and come back, the program crashes.

for example: only pseudo code.

sub maingame()
while key(vk_space)=0
print "Huhu"
wend
end sub

sub simple()
if     key(vk_return) and cury=100
do nothing
elseif key(vk_return) and cury=112 
maingame
elseif kye(vk_return) and cury=124
exit sub 'or return'   
endif
end sub

Done

my solution:
WinEnd: ExitProcess 0,   but I have not any FreeLibrary!

I think InitSound: is being interpreted as a label.

You can either place a space between the name and the colon InitSound :
or insert a pair of brackets InitSound():

I will check the parsing sequence to see if this misinterpretation can be avoided.

The pseudocode looks okay.
Equivalent test:

Code: OxygenBasic

1. sub f()
2. '======
3. do
4.   print "ok"
5.   exit do
6. end do
7. end sub
8.  
9. sub g()
10. '======
11. sys a=3
12. if a=1
13.   '
14. elseif a=2
15.   '
16. elseif a=3
17.   f : a=0
18.   exit sub
19. end if
20.  
21. end sub
22.  
23. g
24.
