Iīve compiled a program with several printf sentences in standard
output without any error or warnings, but in execution, before a
simple printf sentence the program chashes with the next messages:
   - Exit code 255 (000ff) in a Rhide window
   - The contents of register in stderror window
   - In Rhide message window:
         Call frame traceback:
         in function printf+27
         ptest(123) in function main
         in function __crt1_startup+138
Iīm not an Djgpp programmer, but itīs a rare error for me, if
someone can help me, mail me please (joseanmo AT unex DOT es), i canīt
continue with my work. Thanks.

e ALLEGRO bitmap only if know where each line of data 
is stored and what format it is stored in.

A quick read of the ALLEGRO documentation with particular reference to 
the bmp_write_line() function should answer all of your questions. For 
example, if the bmp was in 8-bits-per-pixel format, as mine are, and your 
bitmap was simply the same.... then calling bmp_write_line to get the 
address of the first line of data in the bitmap, then moving your data 
into that position, would do the job nicely.

Hope this helps.
