The backslash character (\) allows you to continue a command line on the

following physical line. When used in this way, the backslash is referred to as a

line continuation character. The line continuation character makes it easier for

you to read the script file. The maximum command line size is still restricted to

255 characters.

Example 2

The following example shows an if command using the backslash character:

if $num = 1 then ; \

echo “The number is 1”;

We recommend that you indent the additional commands to make the script file

easier to read. Also, if there is a large amount of code following the

if command,

use a

goto command to branch around the conditional code.

Example 3

The following example shows an if command with a goto command:

if $num !=1 then ; goto :IF_10:

echo “the number is 1”;

:IF_10:

Example 4

The following script shows how the if command is used to pass parameters into

the script file.

echo “Number of parameters entered on run line: $#”

let index = 1

:LOOP:

if $index > $# then; goto :LOOP_END:

echo “Parameter $index: ${[$index]}”

let index = $index + 1

goto :LOOP:

:LOOP_END:

To test whether a variable is defined, use the if command with the following

syntax:

if $?

<variable_name>

where 1=defined.
