The C51 pre-processor treats the "#" character as the "Stringize" operator. How do I override this operator when desired? For example:
#define X mov A,#10
mov A,10
mov A,#10
Sorry for the "Studio Tech" moniker -- that is the default name on this machine. The advice for using a separate ".asm" file (i.e., the A51 "macro" directive instead of "#define") is certainly a workable solution. We do have occasion to generate in-line assembler within C programs and find that a couple of simple #define statements within the ".h" header file is a bit easier to maintain when extensive assembler code is not needed. Regardless, it would still be useful to know if it possible to generate a "#" from within a #define macro when using the Ax51 assembler. Regarding ANSI compliance, the A51 User Manual does offer the following two caveats on page 158: NOTES The Ax51 macro assembler does not accept C escape sequences like "\n", "\r" or "\x0d". You need to replace these characters with hex values. Unlike the Cx51 compiler, multiple strings are not concatenated to a single string by the Ax51 macro assembler. Therefore you need to separate multiple items with a comma when using the Ax51 macro assembler. I just wish I knew what either of these restrictions meant in terms of actual code construction! As far as I can tell, the C-macro preprocessor within A51 does not expand escape sequences or "hex values" at all.
hi, Regardless, it would still be useful to know if it possible to generate a "#" from within a #define macro when using the Ax51 assembler. If you use the assembler and needs with such definitions then I suggest you to use macro. For example:
XCOM MACRO mov A,#10 ENDM
#define XCOM(x) MOV A,x //... somewhere in program: #pragma ASM XCOM(#10) #pragma ENDASM
