.sdef
Define Assembly-Time Constant
6-26
Syntax
symbol .sdef value
Description The .sdef directive functions in the same manner as the .set directive; howev-
er, .sdef can redefine the symbol name multiple times without generating an
error. All instances of .sdef symbols are stripped from the symbol table at the
end of pass 1 analysis. When used with the .if directive, .sdef can conditionally
assemble included blocks of code. This is useful for turning on and off included
library functions.
-
The symbol must appear in the label field.
-
The value must be a well-defined expression; that is, all symbols in the ex-
pression must be previously defined in the current source module.
Example This shows how symbols can be assigned with .sdef.
VarA .set 15 ;
VarB .sdef 0xAAAA ;
.word VarA, VarB ;
VarB .sdef 0x5555 ;
.word VarA, VarB ; Note the VarB value change
