with fasm's display directive everything is regarded as a string and its tricky to echo numbers.

I think there needs to be a directive to echo numbers, its a bit severe for users to have to hack the echo of numbers

also there needs to be a way to echo filename and line_number of the display command, eg with C there are 2 inbuilt symbols __FILE__ and __LINE__

perhaps if these could be implemented for fasm,

envisioned usage example is:



this macro will intercept any uses of the int asm instruction and
will echo which file, line number and the argument of int

what's the need for this?

There are already some threads around here that have patches to use %L to give the current line number (as a number, not a string). The filename would be a little bit trickier (it is a string) but is probably also doable.

the need is to catch risky constructs,

eg I wanted to use single stepping, but int switches off

single stepping,

thus I needed to locate where int was used,

I need fasm to display the file and line number and the

interrupt vector.

but I dont want to know about usages which arent referenced,

eg commented out etc which word search would locate.






its quite basic functionality, and should be built in,

furthermore it should be quite straightforward to implement

within fasm. implementing it in macros is highly inefficient


look at C's printf, that has strings, characters, ints, hexadecimal etc

YOU tell me whats the need for all that in C


printf( "arguments %s, %x used in file %s line %d\n",
string_variable, number_variable, __FILE__, __LINE__ ) ;

where C is a bit limited is echoing things at compile time

the way fasm display is used.

when I use this stuff with C I have to catch the problems at run time,

with fasm I can catch such things at compile time which is more useful.

FreshLib have advanced "disp" macro that displays numbers as well as strings.
You can find the source and documentation here.
