I sometimes use the display command for
user level warning messages,

it would be useful to have some inbuilt symbols that will
give the file and line number at the point of invocation eg:

an include file: xyz.i
Code:
macro  xyz  number
  {
   if number > 5 
           display  number, ' too big, file: ',__file__, ', line: ',__line__
   end if
   mov ax,number 
   }
    


and a source file: uvw.asm:

Code:
f:
   mov bx,10
   xyz 10
   ret
    


here when I compile uvw.asm, I want the following error message:

10 too big, file: uvw.asm, line: 3 Razz

where although the macro is defined in xyz.i line 1,
it is invoked in uvw.asm at line 3 so the error message needs to
give the file + line of invocation,

here I am asking or suggesting for inbuilt variables __file__ and __line__
which give these 2 numbers for the outermost invocation location, Laughing

because if it gives the innermost invocation position that doesnt help
locate the error,

my guess is that it probably could be implemented by defining an internal variable at each macro expansion just on the first pass of the compiler,

ie whenever the compiler sees a macro on the first pass it can insert
an internal equ like:

__file__ equ 'thisfile'
__line__ equ 123

that way on further passes the location info should be propagated
correctly,

Shocked

As for line number see http://board.flatassembler.net/topic.php?t=1154


as an alternative suggestion, can you implement
a command display_location

so that eg:

Code:
display_location
    


would echo something like:

file x.i line 3, in file y.i line 10, in file z.i line 100, in file f.asm line 20
Razz
?

that would be more useful in a way,
fasm must have some such function inbuilt for its own error messaging,
