i guess i havent get the information about win32a.inc, win32ax.inc and win32axp.inc correctly.

the code below can be assembled without problem
-----------------------------------------------
Code:
format PE console 4.0
entry exit

include '%fasminc%\win32a.inc' ; notice: win32a.inc is used here

section '.code' code readable executable
  exit:
           invoke ExitProcess, 0

section '.idata' import data readable writeable
      library kernel32, 'kernel32.dll'
  
    import  kernel32, \
                        ExitProcess, 'ExitProcess'
    

+---------------+
| MS-DOS prompt |
+---------------+
G:\learn\fasm>fasm e1.asm
flat assembler version 1.54
2 passes, 1536 bytes.

#####################################################

this code will generate error if i try to assemble it
-----------------------------------------------------
Code:
format PE console 4.0
entry exit

include '%fasminc%\win32ax.inc'    ; fail with win32ax.inc and win32axp.inc

section '.code' code readable executable
     exit:
           invoke ExitProcess, 0

section '.idata' import data readable writeable
      library kernel32, 'kernel32.dll'
  
    import  kernel32, \
                        ExitProcess, 'ExitProcess'
    

+---------------+
| MS-DOS prompt |
+---------------+
G:\learn\fasm>fasm e1.asm
flat assembler version 1.54
D:\ASM\fasmw154\INCLUDE\win32ax.inc [4]:
format PE GUI 4.0
error: unexpected instruction.


will fail also if i change it to '%fasminc%\win32axp.inc'
please guide me on how do i know when i should use win32a.inc or win32ax.inc
or win32axp.inc :?

win32ax == win32 ANSI Extend ; i suppose
so, how come the extended version fail?

sincerely,

Using win32ax.inc, you should not specify format and entry point.... Try this:
Code:
include '%fasminc%\win32ax.inc

.code

  exit:
    invoke ExitProcess,0

.end exit

yup, the win32ax.inc does specifies the format to PE GUI 4.0
so to specifies it one more time will cause that error (i suppose)

but does this imply, if i want to use the CONSOLE API, i should choose the win32a.inc?

em... could somebody let me know, what are the "overhead" of using the win32ax.inc? if there is one.

There is no overhead on the executable.
With win32ax.inc only the syntax is slightly different (more high level style) and is for building GUI applications.
With win32axp.inc the assembly time increases a little because of API parameter count checking.

please confirm, does it means, using win32ax.inc is better, coz one can switches between the styles (high level style or PURE style), unlike using win32a.inc where one is subjected to code all in the PURE RAW style. and he got to do lot of dirty works if he changes his mind latter to use the high level style.

em. does this implies that the default entry or starting point for those executable which assembled under win32ax.inc is the ".code" section?

You could include the HLL constructs macros whenever you need to use them.
I find it more flexible the win32a.inc, but you don't need to do dirty tricks on passing between one or another. If you mix styles probably you get a less readable source that however got compiled but is less maintainable.
The best thing is that you choose the style you find more comfortable and stick to it for all across the source.
