The debugger supports a simple macro processor. Twenty-six variables, named "A" through "Z", are available to be assigned to arbitrary strings. You do this with the command:
variable = string
where the "=" must appear in column two. After a variable is assigned, you may use it in any command by specifying the variable name with a "$" in front of it. This provides a convenient way to assign a long symbol name to a shorter string.
For example, if the symbol "EMPLOYEE-NAME" is often referenced in a debugging session, the following commands will assign this to the variable "X" and display the contents of the name:
x=employee-name d $x
Macros may not be nested.
