Dear Gary Thomas,
Thank you very much. But I am a bit consfused. I would like to know
where I need to modify that. So how user can change the memory layout
if he wants to change ?
I not sure that I am suppossed to change the *.ldi files. So am I
suppossed to change the size in *.h or *.mlt file and recompile
again ?
Thanks & regards,
Maxin B. John
