I am tring to compile a unit that defines some bios variable which does compile under TP 7.0. However when I use gpc I get the following messages.
bios.pas:18: warning: variables at absolute adresses may cause problems bios.pas:18: missing semicolon bios.pas:18: parse error before `:'
Part of the coding is as follows. INTERFACE CONST BiosSeg = $40;
VAR ScrnCols : BYTE ABSOLUTE BiosSeg :$4a;
Can anyone please tell me how can I rectify this problem.
Thanks
