Re: [Gnuplot-info] name of current script

[Robbie M. <ro...@ac...>]

Hello Thomas, hello all

I guess I was being a bit cryptic about my suggestion
regarding input that was either redirected from 'stdin'
or piped from another command.  In this case,
GPVAL_LOAD_FILE should be assigned "-".  Which suggests
that perhaps GPVAL_FILE would be a better name for this
variable, because 'stdin' is a type of file in the sense it
gets file descriptor 0.

Can I recommend this concept gets developed and added
to the mainline codebase.  Hint!

thanks
Robbie

if there is no load file, then GPVAL_LOAD_FILE is
undefined, i.e. not existing, and this can be tested
using the 'exists()' function:

if (exists("GPVAL_LOAD_FILE")) print GPVAL_LOAD_FILE
