The information in this article applies to:
- Microsoft Macro Assembler (MASM), version 6.1
-------------------------------------------------------------------------------
SYMPTOMS
========
If two or more values known at assembly time evaluate as TRUE, .IF (below) will
add a JMP instruction. In this first example, only the NOP is assembled:
.IF 1
nop
.ENDIF
In this second example, a JMP instruction is added:
.IF 1 || 3
nop
.ENDIF
If you use a register, as in this third example, the result is a conditional JMP
to the location following the .IF:
.IF ax || 3
nop
.ENDIF
The code runs as expected, despite the extra instructions.
RESOLUTION
==========
To eliminate the extra generated code, replace the "||" with an "OR".
STATUS
======
