to be able to get the asm source file name and line number from source

if we have these information, say in some kind of str, then the error handling can be improved, because if the compiled program got an error or exception
then we can print out the source file name and the line number

for me it was wonderful, i don't know the others

Im sure this is available. Please ready the doco.

Something like this was once discussed here: http://board.flatassembler.net/topic.php?t=1154

Will there ever be a feature to merge equally named sections into one such
that it is possible to declare multiple code or data sections having the same name and
flags?

I've been answering it dozens of times (perhaps it's time to add it to FAQ): this is the linker's job, not assembler's. To do any section merging and things like that you have to use object output, and then some linker. The special fasm's formatters that create executables directly are provided to allow making executables without linker, but not to replace linker - with them there's the rule, that everything in output file reflects exactly the order of declarations source file, thus giving you the power to arrange the executable exactly as you need (at low level).

really, add it to FAQ

Thank you for answering the question again. Next time I will first search the forum before
asking a possibly already answered question.
