Macro Preprocessor 2−63 − An identifier Is expanded in the same manner as it was specified as an actual parameter. Example: DB, byte−var − A string A macro−name in the string is expanded first when the actual parameters are used. Example: "13" −> 13, "1 + @VARS5 +3" −> 1 + 05h +3 − A macro−name In normal mode, the macro−name is expanded in the actual parameter. In literal mode, the macro−name itself appears in the actual parameter and is expanded first when used. Example: @MC_VAR, @*MC1(dw). − A parameter of an actual macro call. This allows parameters to be further reached. 2.7.1.2 DEFINITION OF A MACRO VARIABLE WITH SET Syntax: @SET( macro−variable, expression ) A macro−variable represents a numerical value. Its expansion always results in hexadecimal representation. This variable can be used similar to a macro call (in assembly statements, in a macro call definition, in actual parameter lists of a macro call, in expressions, during the definition of a macro−string in the definition string). If an actual parameter is a number, this can be used in the macro−body using the corresponding formal parameters, similar to macro−variable. 2.7.1.3 DEFINITION OF A MACRO STRING WITH MATCH Syntax: @MATCH( macro−string, [macro−string, ] string ) MATCH defines a macro−string in the sense of simple text replacement, or it processes text lists. • • • • • • • •
