Error when running active code

[mattestion]

When I try to run the code by selecting "Run Active Code", LB opens but then gives the message:

Runtime Error: file not found:
C:\Users\M&M\AppData\Roaming\Liberty BASIC Pro v4.04\liberty.exe
lb4tutorial.lsn
(see error.log for more information)

Here is the error.log:

I set the path to LB in Options as "C:\Liberty BASIC Pro v4.04\lbpro.exe".

Are you trying to open and run the lesson file in LBWorkshop? Files with *.lsn extension do not run in LBWorkshop. I don't know if Liberty BASIC is set up to run lesson files from the command line, and it never occured to me that folks would try to run or edit lesson files in LBWorkshop.

They are actually XML files, not simple code files.

Sorry! Try running the lesson in the Liberty BASIC IDE directly.

Okay, I have figured out part of the problem. LB by default is set to open the welcome.bas file. At the end it has code to run the tutorial.

nomainwin
run StartupDir$+"liberty.exe lb4tutorial.lsn"
end

So when LB was opened by Workshop it ran that code and triggered the error. The file structure has changed in LB so it does not find the tutorial, plus the .exe is a different name.

I changed the option in LB to open no file. When I click "Run Active Code" in Workshop, with an LB bas file, LB opens with no error but is blank (untitled.bas). Then I set LB to open most recent file. Now LB opens and compiles the code. The problem is that if I open another bas file in Workshop and tell it to run it, LB still opens the previous file I was working with. Is it possible the command line in LB Pro is different?

That's interesting. I would not expect the setup options of the Liberty BASIC editor to interfere with running it from the command line. This sounds like a bug in LB Pro, since it would fail equally when run from any external editor, or even from a bat file in the DOS "run" menu.
