Hello,

I have the following code which works kindof not as i expected:
Code:
Ver equ bbb

if Ver eq aaa
   x equ a
   display "aaa"
else if Ver eq bbb
   x equ b
   display "bbb"
else if Ver eq ccc
   x equ c
   display "ccc"
end if

display x           


As i would expect, the second block is compiled, so "bbb" is displayed in the message window, but the 'display x' line compiles as 'display c' instead of 'display b'.
Actually, it seems the value of Ver does not impact the value of x, x equ c is always what gets compiled Shocked

Moreover i get an error for the last display command, which i could live with, but would be nice to know how to display numerical values like this:
Code:
a equ 0x1234
display a
    


thanks again,
pepe

The if, else and end if are assembler blocks. Using equ is a preprocessor block. The preprocessor ignores the if/else/end if and always executes the equ. To make the preprocessor conditional you can use match.

Thank you. That explains everything.
In the meantime i found the answer to the 2nd question in the manual, dunno how i overlooked that.
BTW, i think it would be good to keep the log window displayed at end of compilation to see the displayed messages. If there is no error, it disappears, so i have no idea about the output of the display lines. (using FASMWARM)
