Enable or disable & macro substitution
SET MACROS ON | OFF | (<expL>)
If SET MACROS is ON, then & macros are substituted when command lines are read. If SET MACROS is OFF, then no macro substitution is performed. This command can be used to marginally accelerate program execution. Also, macros are normally substituted in the TEXT ... ENDTEXT command. Setting MACROS OFF disables this. See the & function for more details concerning macro substitution. By default MACROS is ON, so macro substitution is performed.
