How to display all TCC internal variables

[Eric Pement]

Is there a single command that will display a list of all TCC Internal variables, just like set (with no arguments) will display a list of all environment variables? I am willing to add a plugin to solve this.

 

[Joe Caverly]

A list of all internal variables is available from the SDK (https://jpsoft.com/downloads/sdk/sdk.zip)

The SDK contains the file Internal_Variables

This is the contents of the Internal_Variables file;

Also, Command_Variables. These two files together cover the lot. There are over 300 total!

 

[Joe Caverly]

Thought I could display the values of each of the internal variables,
but it stops at _batchlabel ;

R:\>do theVar in @Internal_Variables (echo %theVar %[%theVar])
_4ver 36.51
_? 0
_acstatus 1
_admin 1
_afswcell
_alt 0
_ansi 1
_batch 0

Thanks, everyone. Add these 4 to the list of Internal_Variables and Command_Variables. They are not anywhere else:

%! Last argument of the previous command
%? Exit code, last external program
%_conpty 1 if running in a pseudoconsole; else 0
%errorlevel Exit code of last program (the only one that does not begin with underscore!)

I also discovered a spelling error on TCC Internal Variables by Name : a variable name is listed as _msg_checkbox, but its real spelling is _msgbox_checkbox .

I'm going to create a personal table to list these . . .

_batchlabel is only valid in a batch file.

 

[Joe Caverly]

Indeed.

@SETLOCAL
@ECHO OFF
if isdir r:\temp set temp=r:\temp

do theVar in @Internal_Variables (echo %theVar %[%theVar])
ENDLOCAL
quit

Output:
