Sounds fair.  However, in a DOS environment, you may have to use fmalloc() or
farmalloc() depending on the memory model and compiler.

Actually, this MAY be legal (never tried it, but what the hell):

void main ( void )
{
char *TheArray=(char *)malloc(BIG_NUMBER);
char  TheArrayAgain[]=TheArray;               // Is this legal?
}
