Deleting Macros 
There are several mechanisms provided by PCL macro control 
for explicit deletion of macros from user memory. These include 
commands to delete all macros, all temporary macros, or an 
individual macro by reference to its macro ID number, using the 
Macro Control command described later in this chapter.
Both temporary and permanent macros are deleted from memory 
whenever the printer’s power is turned off.
Macro ID 
The Macro ID command specifies an ID number for use in 
subsequent macro commands.
E
C
 & f # Y
#  =Macro ID number 
Default = 0
Range = 0 - 32767
This number is used in subsequent macro operations.
The factory default macro ID is 0.
Example
To establish a macro ID number of 5, send:
E
C
 & f 5 Y
