The load command must be the last command on a multi-command line.
Syntax:
load "<input-file>"
The name of the input file must be enclosed in quotes.
The special filename "-" may be used to load commands from standard input. This allows a gnuplot command file to accept some commands from standard input. Please see "help batch/interactive" for more details.
Examples:
load 'work.gnu' load "func.dat"
The load command is performed implicitly on any file names given as arguments to gnuplot. These are loaded in the order specified, and then gnuplot exits.
