The RunMenu command runs a menu option just as if it were selected manually. Square brackets "[ ]" symbolize entries to be replaced.
Usage: RUNMENU=[MenuPath] (where MenuPath is the name of the selected menus, each separated by a dash).
Example:
RUNMENU=Transaction-Edit/View/Print-Sales Invoice-Number.
This example displays the Sales Invoice Lookup List, sorted by Transaction Number (which is equivalent to typing [Alt]+[T][E][I][N} on the keyboard).
