Lance,

I agree with Jay. (He was brief as never :-).

I'd like to clarify the SET directive application.

The 8051 cross-assembler directives are used to define symbols, reserve memory space, store values in program memory, select various memory spaces, set the current segment's location counter and identify the end of the source file.

Similar to the EQU directive, the SET directive is used to assign a value or implicit operand to a user defined symbol. The difference however, is that with the EQU directive, a symbol can only be defined once. Any attempt to define the symbol again will cause the Cross Assembler to flag it as an error. On the other hand, with the SET directive, symbols are redefineable. There is no limit to the number of times a symbol can be redefined with the SET directive.

So the SET is instruction to the assembly during the translation not during the execution time.

Please make allowances it in your job.

Good luck,

George
