Hello,
I would like to write a log-file while compiling, in an non-overwriting way.

Is there a possibility to append some lines to a file (or write it before the actually file?)?
I would prefere to write it before the actually file, like:

log.txt:
Code:
20.12.2010, 18.11:
Parameter 17
Function 2, number 12
    


becomes:
Code:
20.12.2010, 18.31:
Parameter 11
Function 2, number 11
20.12.2010, 18.11:
Parameter 17
Function 2, number 12
    


I have searched for that in the manual, no success.

Is there also a possibility to check whether the file already exists? Because the "file" command fails if the file does not exist (if i want to display the old log.txt content).


Thanks for help!
Andreas

In the command line version (fasm.exe) you can use the display directive to output code to the terminal. Then just redirect the output to append to a file.
Code:
c:\fasm> fasm MyUberProggy.asm MyUberProggy.exe >>log.txt

Thank you!

I always use the FASM GUI (ctrl+f9), so is that possible with the GUI too?

Not that I am aware of. The GUI will print displayed stuff to a dialog window. Use the command line version, it is also in the Win32 download with fasmw.

Thx revolution for the fast answere.

I finally thought I had a solution:

Code:
format binary as 'log'
db "Function 1"

format binary as 'exe'
code


format binary as 'log'
db "Parameter 2"

format binary as 'exe'
more code    


But that does not work, too - "unexpected instruction"

Do you know any way to make that working? To write to a log file?

You can only have one format statement per assembly invocation. You would need to make four separate .asm files and assemble each file individually.
