If that's just for a single scalar it's not enough I'm afraid -- although I
guess one could simply use it as an index type value.
About getenv(): I had looked at it, but AFAICS it would only give me the home
directory, not the gretl CWD.
Sorry, I wasn't clear. I meant something like this:
<shell>
jack@asus-nb:~$ X="{1,2,3}" a=11 gretlcli -q
gretl version 2017a-git

"help" gives a list of commands
Type "open filename" to open a data set
? a = ngetenv("a")
Generated scalar a = 11
? sx = getenv("X")
Generated string sx
? X = @sx
Generated matrix X
