## evaluate

The evaluate command executes gnuplot commands contained in a string or in a function block. Newline characters are not allowed within the string.

         evaluate "commands in a string constant"
         evaluate string_valued_function( ... arguments ... )
         evaluate $functionblock( ... arguments ... )

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 function blocks and substitution macros for other mechanisms that construct or execute strings containing gnuplot commands.
