Hello! I don't find instructions about work with files in win32 fasm. I want make program with analog function php:
1. file_get_contents and explode in array by line
2. file_put_contents (implode string line in array, and write to file)
3. multithreading in FASM
4. for, foreach, while in FASM

Thank you.

I think you will need to use Win32 API?

CreateFileA, ReadFile, WriteFile....

FASM has high level macro extensions to make loops, like those below:

Code:

.while
.endw

.repeat
.until

I wish that these would also have the "break" and "continue", but OK.
For the multiple threads also API is needed:

Does this work for "break" and "continue"?

Code:

macro .breakw
{
  jmp __ENDW
}

macro .continuew
{
  jmp __WHILE
}
