Help! How can I break _DATA_GROUP_ segment into two parts? Thanks!
Thanks Erik "PS, just curious why?" Because _DATA_GROUP_ segment too large to be locate behind bit segment, but there is "GAP" afore it.
in C split DATA variables into two files not work.
in C split DATA variables into two files not work. I think I misstated, I just looked (did it a year or do ago and eveidently forgot I did it in assembler like this:
;;//////////////////////////////////////////////////////////////////// ;; ;; FILE: SZDATA.A51 ;; ;; Copyright ;; ;; Overcome the Keil inability to save DATA parts in gropus lexx than "hole" $NOMOD51 PUBLIC GCDXdestListBeg PUBLIC GCDXdestListEnd PUBLIC GCDXprmsListBeg PUBLIC GCDXprmsListEnd PUBLIC GCDXcurrListBeg PUBLIC GCDXcurrListEnd PUBLIC GCDXothListBeg PUBLIC GCDXothListEnd ?DT?zdataf SEGMENT DATA RSEG ?DT?zdataf GCDXdestListBeg: ds 2 GCDXdestListEnd: ds 2 GCDXprmsListBeg: ds 2 GCDXprmsListEnd: ds 2 GCDXcurrListBeg: ds 2 GCDXcurrListEnd: ds 2 GCDXothListBeg: ds 2 GCDXothListEnd: ds 2 end
combined with this in the c

Because 00002CH + 000056H > 00007FH, it is overflow. if 000056H is split into 000003H and 000053H, then 000003H fill the "GAP" (00001DH to 00001FH) and 00002CH + 000053H = 00007FH, it will be OK. How can I do that? Be careful: it is _DATA_GROUP_
How can I do that? EXACTLY as i did show you above.
Be careful: it is _DATA_GROUP_ so what, you need two DIFFRENTLY NAMED sgements holding the dats, it is STILL "DATA"
if you can not figute out how to 'adjust' the example to 3 bytes, you should not be playing with this.
here is the proof
