Hallo!

I'm having problems with running a program using Allegro under DOS/ 
CWSDPMI. There are no problems under Win95.

Well, first I got error 0006. I looked it up in the FAQ, but the described  
crt0-thing didn't work (same error).
Symify told me that the error is in the 'set_clip' function  
(_set_clip+141). It turned out to be the "init_dialog"-procedure in my  
program code (one of the Allegro-GUI-routines).

Then I looked up the 'set_clip' in the 'init_dialog'-procedure (sourcefile  
gui.c), threw the "set_clip(screen,0,0,SCREEN_W-1,SCREEN_H-1)" line out  
and recompiled Allegro.

And now the problem is even bigger (maybe ;). Now I get error 0004 with  
the following Symify-output:

 _button_proc+35, line 205 of padd.c
 _init_dialog+237

padd.c is my sourcefile. Line 205 is "d->dp = layout[k].dat;" (d->dp is a  
void pointer of the dialog routine [points to a bitmap for a d_icon_proc- 
Button-Procedure]).

I don't know what's wrong with the code, so I hope that anybody here is  
able to help me getting this thing work under pure DOS ;-)


Bye,
    Jens
