Ok, maybe I´m too happy for making a asm app and writing my own idata
section, but here is another example =)

It shows a message box and then quit.

/* Hello world to create a symbian os executable on assembler */

        .file   "hello.s"
        .text
        /* Variables */
mymessage:
        .ascii  "My Message\000"

        /* Entry point for Symbian OS executables */
        .globl _E32EXE
_E32EXE:
        /* Entry point for MS Windows */
        .globl main
main:
        /* Entry point for GCC */
        .globl [EMAIL PROTECTED]
[EMAIL PROTECTED]:
        MOV   $0, %EAX
        PUSH    %EAX
        MOV     $mymessage, %EAX
        PUSH  %EAX
        MOV   $0, %EAX
        PUSH    %EAX
        PUSH  %EAX
        CALL    MessageBoxA
        MOV   $0, %EAX
        PUSH  %EAX
        CALL    ExitProcess
        LEAVE
        RET
        NOP
