Boolean Logic and Relational Operators
OL-5647-02
To build structured command blocks, use the if and while branch commands. The
if command creates script branches based on the results of previous commands.
The while command is a looping mechanism. Both commands facilitate efficient
scripts with fewer repeated actions.
Use both these branch commands with the endbranch command, which indicates
to the CLI the end of a logical block of commands. Any branches created without
a terminating endbranch command produce a script logic error and possibly a
script syntax error. For information on script errors, see
Termination"
later in this chapter.
You can nest a maximum of 32 levels of branch commands.
You can use each of the following operators with an if, while, or modify
command.
The Boolean logic operators used with branch commands are:
•
AND - Logical AND
OR - Logical OR
•
The relational operators used with branch commands are:
GT - Greater than
•
LT - Less than
•
== - Equal to
•
NEQ - Not equal to
•
LTEQ - Less than or equal to
•
GTEQ - Greater than or equal to
•
