pelles c 13.01
a1 one:3  a1 zero:16
a2 one:3  a2 zero:32

WHY? and which is right?

Confirming Pelles C 14.1 now reports
a1 one:14  a1 zero:1
a2 one:30  a2 zero:1

Add-ins / Re: SelectLine

Last post by John Z - May 15, 2026, 05:53:57 PM

Well I guess idle for the moment - so here is a better version of SelectLine Add-in.  Version 2 will do both partial line selects and whole line select (when cursor is anywhere in the line).

Operation mode is user configured using Main Menu Tools, Options, Add-ins.
Select the add-in 'Click to select line', then click the Options button on the right.  Answer the dialog question, this will configure the select line mode.  Change anytime using the same procedure.  The mode is retained even when Pelles IDE is closed and reopened. 


Project sources attached, easy to build or use existing SelectLine.dll

Hi Erol,

Basically a nice idea to avoid using msvcrt.dll in some projects with poasm.

Hi Timo,

I guess you are referring to the duplicate symbols issue. Polink cannot link those combined object files. This is why I used MS Link. I think my example should be fine as it's a very simple one.

Sadly have to say, that is a bad idea, as no COMDATs

Ld, the GNU linker has an interesting feature, it can combine object files to create one monolithic object file. The example below combines StdOut.obj ( function to write to the console window ) and the dependency StrLen.obj ( string lenght calculator ) to output one file named Modules.obj

Add-ins / Re: SelectLine

Last post by John Z - May 10, 2026, 12:51:20 PM

Minor update to build a version that always selects the entire line regardless of the cursor position in the line.  To build this way define ALWAYS_WHOLE before building.

Original build a cursor in the middle will select from the cursor to the EOL.
An ALWAYS_WHOLE build a cursor in the middle, or anywhere in the line, selects the entire line.

Newer source zip include below for version 2
