Hello
I just try to use PAL variables. Start Console2 application, type
echo %PAL:Drive%
and see %PAL:Drive% label instead drive letter
This is question: how to use system variables with colon ":" in child processes?
Example: when i type ECHO %userprofile% i see path to my windows user profile.

This variable is use in writing launcher ini and custom code only. It will not work outside the PAF launcher.
This is not true. You can see this by opening Console2 and there typing command:
ECHO %PortableApps.comDocuments%My problem only in colon.
While that may work for PortableApps.com variables, the PAL ones are specifically designed to be used within a single App's launcher, and designed not to be accessed externally.
This is, as I said, by design, so that individual apps are not affected by one another. It will not be changed.
[EDIT] With that said, if you can explain more about what you're trying to achieve, there may be other ways to accomplish your goal.
I just want to access a variable from a child process.
For variable
PortableApps.comDocumentsit works, from anywhere with a colon - no.As i wrote above (example),
ECHO %PortableApps.comDocuments%gives a valueE:\Documentsecho %PAL:Drive%displays%PAL:Drive%http://funkyimg.com/i/29fin.png
The PAL:Drive, PAL:LastDrive, etc variables are internal to PAL itself and are not accessible to the child process. They aren't for the child process. They are for PAL itself. This is by design.
If you want PAL:Drive accessible to your child process, make an entry of PALDriveForChild=%PAL:Drive% in the Environment section of the launcher INI and then use that variable.
Sometimes, the impossible can become possible, if you're awesome!
This applies only to a variable with a colon (
%pal:variable%)? Because the variables to point (%PortableApps.comVariable%) I get access without problems.My question is for the colon, not access to system variables.
For example, if you type the command
SET variable1.variable1=test1and then
ECHO %variable1.variable1%the screen displays the message
test1But if you type
SET variable1:variable1=test1and then
ECHO %variable1:variable1%the screen will not
test1but for some reason%variable1:variable1%Here in the middle of the colon is referred to http://www.computerhope.com/sethlp.htm (Search on line
%PATH:str1=str2%), but nothing concrete yet and I have not found.So, just don't use colons.
All the PAL: variables are *purposely* internal to the app launcher only. Don't use them in your base app. Period.
PortableApps.comDocuments et al are purposely external. They're set by the platform for use by app launchers and apps.
If you're having issues with colons otherwise, I'm not sure why. It doesn't really matter. I would suggest just not using them.

In any case, thank you for your answers
just wanted to, from one application to run other applications (without absolute paths) e.g. Open With plugin for Firefox or similar plugin for AIMP.
