Start recording commands within a named file for later re-use as a macro. After the file is opened all subsequent commands are recorded in the file until the STOP MACRO command is issued. The macro can later be run with the MACRO command. If the MACRO command itself is used, the contents of the macro are written into the new macro file. The manner to define and use macros are explained in Section 19, Page . (Also see STOP MACRO, Section 15.110, Page and MACRO Section 15.56, Page .)
