hi!

i want to define structure, but avoid redefinition, but have no success.

the first attempt i've done:

Code:

if not defined CHARRANGE
    struct CHARRANGE
        .cpMin dd ?
        .cpMax dd ?
    ends
end if

got message "reserved word used"

the second one:

Code:

if defined CHARRANGE
else
    struct CHARRANGE
        .cpMin dd ?
        .cpMax dd ?
    ends
end if

-- "code cannot be generated"

so, what can help me?
or, just thought, i should use one of such variances:

if (defined CHARRANGE)=FALSE
..

if !(defined CHARRANGE)
..

if !defined CHARRANGE
..

?

thanks!

First, read about conditional expressions in fasm's manual.
Second, the solution to your particular problem, which is very fasm-specific is discussed in this article. In short, it should be something like:

Code:

if ~ defined CHARRANGE | defined ..here
 ..here = 1
 struct CHARRANGE
  .cpMin dd ?
  .cpMax dd ?
 ends
end if
