Substitutions
with macros
The Substitution value may also be a replaceable parameter that can be referenced by a macro.
For example, place %1 in the Substitution field adjacent to a variable called “section” in the @ column:
Place @section at the required location in a plot text file, and enter section coordinate values e.g. 1000N, 1020N in the %1 variable of a macro with several PLOT processes.
