[BUG] Installer "string too long" with blank env-vars

[chris]

When trying to set a variable to an existing - but empty - env-var it causes Installer to abort with a "string too long" error.

Eg, save the following code and execute it with Installer:

Code: Select all

(set #test
	(getenv "envtest")
)

(message #test)

now type the following in the Shell:

Code: Select all

setenv envtest ""

Try running the script again and it will abort with the aforementioned error.

This looks like an installer problem.
I'll ask about it, it sounds vaguely familiar.

OK, there WAS a problem with IDOS->SetVar() a long time ago, that was fixed.

However, your report has shown up a problem with IDOS->GetVar() reading an empty string and that has now been fixed so that it returns zero rather than (-1). Hopefully the new version of DOS will be released soon, fixing the problem.

Thanks mate, so it wasn't Installer after all!
