DOCUMENT:Q58864 06-MAY-2001 [masm] TITLE :Using a Macro to Determine the Current Segment PRODUCT :Microsoft Macro Assembler PROD/VER::5.1,5.1a OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Macro Assembler (MASM), versions 5.1, 5.1a ------------------------------------------------------------------------------- SUMMARY ======= The following macro can be used to determine the segment from which the macro is called during assembly of a source file. In the following example, the "findseg" macro is called from within two individual segments named code1 and code2, respectively. The macro then uses IF statements to determine the segment. Then, depending upon the segment, any desired code can be assembled. findseg macro segname ifidn , ; if in segment code1 : ; do what is desired endif ifidn , ; if in segment code2 : ; do what is desired endif endm ; end macro findseg code1 ;macro call in segment code1 . . . findseg code2 ;macro call in segment code2 Note that invoking the findseg macro with the @curseg equate as a macro argument will not yield a true condition for the ifidn expression. The value of "segname" is resolved to the string "@curseg" which, in the example, is identical to "code1".
