I'm trying to use the new MASM macros to emulate their proc syntax. Everything seems to work, but I can't figure out how to declare multiple BYTE buffers as a 'local'. My first attempt--after looking at how the local macros work--was as in test_proc3. The code assembled to adjust the stack as shown. Both .buffer:BYTE,20 and .buffer:DWORD,5 yield the wrong result. test_proc2 yields the correct results.

The way I read the proc.inc file was: varname:vartype,var

How can I do this using the new local format?

Code:

test_proc       proc
local           .buffer:DWORD,5                 ;SUB ESP,4  <- Should be 14h

        ret
test_proc       endp

test_proc2      proc
local           .buffer:DWORD                   ;SUB ESP,14
local           .buffer1:DWORD
local           .buffer2:DWORD
local           .buffer3:DWORD
local           .buffer4:DWORD

        ret
test_proc2      endp

test_proc3      proc
local           .buffer:BYTE,20                 ;SUB ESP,4  <- Should be 14h
        ret
test_proc3      endp

Thanks!

I'm really enjoying the new power of the FASM.

The syntax for local are the multiple varname:vartype declarations separated with commas, you have wrongly interpreted the "match" line (read more about the "match" in the manual).

However, you can do it this way:

Code:

local buffer:BYTE 20 dup (?)

or better for larger local structures:

Code:

locals
  buffer db 20 dup (?)
endl

Note also that there's no need to put the dot in the beginning of name for the locals.

Privalov,

Thanks!

I'm not suprised! Trying to wrap my mind around macros!

Code:

local buffer:BYTE 20 dup (?)

As it should be!

Thanks again!
