It would be too many posts to post all my programs in separate posts. I'll include a link to some of them.
Sad that this thread has gone quiet. Would be interesting to see other people's software.

Here are some of my programs:

Here is another attempt :

Code Select Expand

include SaveRegs.inc

SaveRegs MACRO

    mov     QWORD PTR [rbx],rcx
    mov     QWORD PTR [rbx+8],rdx
    mov     QWORD PTR [rbx+16],r8
    mov     QWORD PTR [rbx+24],r9

ENDM

.data

msg     db 'Hello!',0
msg2    db 'rcx,rdx,r8 and r9 are saved.',0
title   db 'MsgBox',0
title2  db 'Macro test',0

.data?

mainRsp dq ?

.code

start:

    sub     rsp,8+4*8

    push    rsp
    pop     mainRsp

    invoke  main,ADDR msg2,ADDR title2,10,20

    invoke  ExitProcess,0

main PROC uses rsi rdi rbx x:QWORD,y:QWORD,w:QWORD,z:QWORD PARMAREA=4*SIZEOF QWORD

    LOCAL   temp1:QWORD

    mov     rbx,mainRsp
    SaveRegs

    xor     rsi,rsi
    mov     rdi,1

    invoke  MessageBox,0,ADDR msg,ADDR title,0
   
;   The first call to MessageBox destroys rcx,rdx,r8 and r9

    invoke  MessageBox,0,[rbx],[rbx+8],0
   
    ret

main ENDP

END start

Feature requests / ADDIN_ENUM_PROJECT_FILES struc...

Last post by John Z - February 21, 2026, 02:55:09 AM

The Addin_EnumProjectFiles uses ADDIN_ENUM_PROJECT_FILES structure.
The request is to add a flag to the structure and set the flag if the file is in excluded state.
Current there seems to be no method to determine if a file is excluded using the Addin messages.

Addin's can include and exclude but seems nothing is able to report back the state of a source file.

Feature requests / Re: Enhanced editor suggestion...

Last post by PhilG57 - February 20, 2026, 06:41:23 PM

Thanks, but I don't think this is it.  I'm hoping for a capability that, while in the editor, I can know if a particular compiler symbol is defined or not.  A symbol like "_WIN32" or "__32BIT__" or more likely some user symbol defined in the code itself and evaluated (by the preprocessor??) with #ifdef and #ifndef statements.  With this capability I could, while in the editor, know and see which path through the source code the preprocessor and compiler is taking.

I didn't actually look at your suggestion seeing as it referenced .obj (already compiled) files so if I am missing the boat here, please LMK.  Thanks.

Pelles C .chm documentation states

however, the definitions for the _setmode function "mode" parameter arguments

_O_BINARYetc.,

are not in
