Very strange problem,

test.asm is:

Code:


use16
        and ebx, 0ffff0000h

when I try compiling this with 2 versions of fasm,
the one version succeeds and the other doesnt:

G:\fasm>fasm test.asm
flat assembler version 1.67.7 (15360 kilobytes memory)
1 passes, 7 bytes.

G:\fasm>
G:\fasm>fasmorig test.asm
flat assembler version 1.64
test.asm [4]:
and ebx, 0ffff0000h
error: extra characters on line.

You may be wondering why I want the earlier version of fasm,
its because I have a source file with a large number of includes
which the newer version of fasm will not compile.

What things are incompatible with current version? I'm missing some important change from 1.64 to 1.67.10?

[edit] Corrected 1.76.10 to 1.67.10. Sorry, typed to fast Razz

Is it possible it's having a problem with a '\r' character at the end of the line? BTW, if you want to zero out the low half of ebx in 16 bit mode, it's probably faster to just do "xor bx,bx".

I've resolved the problem: Razz

I had installed both versions to the same directory,

by reinstalling the earlier version of fasm to its own
directory it now runs correctly: Very Happy

G:\fasm>fasm1\fasm test.asm
flat assembler version 1.64
1 passes, 7 bytes.

G:\fasm>

here I have installed fasm 1.64 afresh to the subdirectory fasm1,

so it must have been a conflict of system files
