Re: // at beginning of line

Show all headers | View raw

Thanks for ur help, now the program compiles fine.

However when I run it I get this error :
"PRGWMUPP caused a General Protection Fault in module <unknown>0417:1B6F. 
PRGWMUPP will close."

I would like to change the source code to prevent this error, can anyone 
advice how to do it ? I think maybe I need a full C++ compiler not just 
basic C, would you agree ?

Many Thanks
Federico.
