The WHILE statement executes
commands repeatedly as long as a given expression is true. The WHILE statement consists
of the reserved word WHILE, an
expression (condition), commands, and the reserved word ENDWHILE. When NetCI executes a WHILE
statement, the following occurs: NetCI evaluates the expression which
is the condition. If the condition is true, it executes the subsequent
commands in the script file until ENDWHILE
is encountered, and then re-evaluates the condition. When the condition
becomes false, execution resumes at the next statement or command
after ENDWHILE. If the condition is false, the subsequent commands
following this condition will not execute, and flow control skips
to statements or commands after ENDWHILE.

Parameters | |
- expression
Specifies the condition that determines whether
the commands following it will execute. The expression must be in
the following format: identifier operator identifier |
The identifier is a variable
name, numerical value, or known variable (set flag) in NetCI. The
operator is an equal sign (=),
not equal sign (< >), greater
than sign (>), or less than (<)
sign. - commands
Specifies the commands to be executed provided the
expression (condition) is true.
Discussion | |
The INC statement may be
used with the WHILE statement to
increase the value of the expression specified with WHILE.
Refer to the INC statement which
was previously discussed in this section. |
