The evaluate command executes the commands given as an argument string. Newline characters are not allowed within the string.
Syntax:
eval <string expression>
This is especially useful for a repetition of similar commands.
Example:
set_label(x, y, text) \ = sprintf("set label '%s' at %f, %f point pt 5", text, x, y) eval set_label(1., 1., 'one/one') eval set_label(2., 1., 'two/one') eval set_label(1., 2., 'one/two')
Please see substitution macros for another way to execute commands from a string.
