verify symbol definitions. For example:
define ncl symbol NAME = "VALUE"
undefine ncl symbol [ NAME | * ]
show ncl symbol [ NAME | * ]
list ncl symbol [ NAME | * ]
ncl> define ncl sym rc1 = "routing circuit circuit-1"
ncl> show rc1

Name = circuit-1
The first parameter to the define command is the symbol and
all remaining text is the equivalence string (the translation
of the symbol). The symbol can be from 1 to 500 characters in
length and contain any ISO latin-1 characters (?). At definition
time, the equivalence string is not parsed. NCL will parse the
full NCL command and any symbols that form part of the command.
To delete symbols, use the undefine verb. For example:
ncl> undefine Ether,Remote_Node ! To delete specific symbols
.
.
.
ncl> undefine * ! To delete all remaining symbols
.
.
.
You can use "." to mean "the entity used in the last command."
