Hi, I'm new in FASM and I have a problem passing a struc to a macro.

This is the macro:
Code:
macro doRect hDC, rc
{
  invoke Rectangle, [hDC],\    ; handle of device context
                    rc.left,\  ; x-coord. of bounding rectangle's upper-left corner
                    rc.top,\   ; y-coord. of bounding rectangle's upper-left corner
                    rc.right,\ ; x-coord. of bounding rectangle's lower-right corner
                    rc.bottom  ; y-coord. of bounding rectangle's lower-right corner
}
    


And the problem is when I use the macro in this way:

doRect, hDC, rect

FASM throws "Error: undefined symbol"; "instruction: push rc.bottom"

The problem is that rc is not replaced by rect but if I put a space between rc and . then FASM replace correctly but again an error "Error: undefined symbol" "instruction: push rect .bottom"

What can I do to fix it?

Code:
macro doRect hDC, rc
{
  invoke Rectangle, [hDC],\
                    rc#.left,\
                    rc#.top,\
                    rc#.right,\
                    rc#.bottom
}

remember that in fasm "." character is normal part of name, like any letter or digit, not operator to separate structure members. Looking like such operator is only kind-of standard and behavior of "struc" macrodirective.

And since "." is normal part of name, FASM has seen "rc.left" symbol, which isn't equal with "rc" and so it wasnt replaced.

Vid thanks for your reply, I did not know what you say about the dot.

BTW, fasm's syntax highlighting (applied also on this forum) shows you this fact - the special characters (which split words) are shown in blue, and dot isn't.
