"[resume_esp]" and "[resume_eip]" are only defined inside "CalculatorDialog".
... while these two variables can potentially be used out from any errors which use "error_with_source" or directly "assembler_error" (from ERRORS.INC)
what do you think about this Tomasz ?

Code:

error_with_source:
        cmp     [symbols_file],0
    je      assembler_error
...
assembler_error:
      cmp     [hthread],0
 je      error_outside_compiler
...
error_outside_compiler:
        mov     esp,[resume_esp]   ;only defined inside "CalculatorDialog"
        jmp     [resume_eip]       ;if the code comes from elsewhere,
                                   ;it's a crash.

thank you.

Have you see

'entry start' or 'format' in SOURCE\IDE\FASMW\FASM.inc

in SOURCE\IDE\FASMW\FASMW.ASM :
->include 'fasm.inc'
and it had defined

i think it like order include file: system.inc,errors.inc

sorry for my english

ok, understood.

Code:

A)
--
proc CompileDialog hwnd_dlg,msg,wparam,lparam
        ...
  invoke  CreateThread,NULL,10000h,flat_assembler,\
        [ei.pszpath],0,param_buffer
   mov     [hthread],eax ;<-----
   
;-----------------------------
B)
--
proc CalculatorDialog hwnd,msg,wparam,lparam
        ...
.calculate:
 mov     esi,string_buffer
   invoke  GetDlgItemText,[hwnd],ID_EXPRESSION,esi,400h
        lea     edi,[esi+eax]
       xor     eax,eax   ;<-----
        stosb
       mov     [hthread],eax ;<-----
    mov     [source_start],eax

;==============================
assembler_error:
   cmp     [hthread],0
 je      error_outside_compiler
        ...
