I have found, that when I use -finline-functions, I get this wierd
corruption.  So here are the functions:

void WriteDesktop (short int Attrib)
{
short int * EAX, * EBX, ECX;
EAX = (short int *)(Base);
EBX = (short int *)(Base + 4000);
ECX = Attrib;
while (EAX < EBX) *EAX++ = ECX;
}

That works, but when I do this,

void WriteDesktop (char A, short int Attrib)
{
short int * EAX, * EBX, ECX;
EAX = (short int *)(Base);
EBX = (short int *)(Base + 4000);
ECX = Attrib + A;
while (EAX < EBX) *EAX++ = ECX;
}

It always shifts all the bits to high in either the high or low byte.
What is odd, is that this always happens when I do these type of calcs
on about 50+ screen cells, other than that, everything is fine.  When done,
I plan on publishing my TUI, simular to TurboVision, but no C++, you merely
tell the library what you want, and where.  So far, It handles buttons, fields
, windows, desktops, menus, and shortly forms.

Any ideas, feel free to write.
