Hello,
I compiled the same program on my machine (NT4.0 SP3 / Intel Pentium) with
the Microsoft C++ Compiler 4.0. It runs
without any errors 1024 times.
#include <stdio.h>
main()
{
char syscmd[124];
int i=0;
for(i=0;i<1024;i++) {
sprintf(syscmd,"echo %d",i);
system(syscmd);
}
}
With regards
Michael Emrich
