To read a macro file and load the macro definitions into the Worksheet, select Macros, Read Macros from the Tools pull-down menu. In the displayed dialog box, select the macro filename to read and click OK.
The MACREAD command also lets you load a macro file from disk into the current Worksheet. For instance, if you have some matrix-related macros in a file called "tables.mac,"
would reload all the macros from tables.mac into the current Worksheet.
