Three of the 'C' source files in my Project have inline assembler; therefore I have checked the 'Generate SRC' and 'Assemble SRC' options for these files in uVision. This causes those 3 files to translated every time I build the Project - even when they have not been changed. The 'Always Build' option is not checked. How can I make it translate these files only when needed - like it does with all the others? uVision v2.12 C51 v6.12b A51 v6.13b Full, dongled product on WinNT4
