Hi,

The FAQ sez that we have to wary of the base address changing after a
malloc(), system(), spawn...() etc. call. My question is that when the base
address changes, dont all pointers go haywire (including near pointers,
etc). Could somebody point me to a good online introduction or tutorial
describing prot. mode mem. management (and everything else if possible).

And one other thing. My friend uses a Watcom compiler and guess how he uses
video mem. 

char *p=(char *)0xA0000; *(p+something)=color. 

thats it. No farptr functions or anything. how does watcom manage this. I
thought maybe watcom was always in nearptr mode, but if so, wont the base
address need to e recalculated or something? 

Bye,
