gosub

The

gosub

command calls a subroutine inside the same script file. It must be the

last command on a line. A subroutine begins and ends with a colon (:). You can

nest subroutines up to 10 deep. You use the

return

command in a subroutine to

return to the calling routine. When the

return

command executes, the script

interpreter begins executing the instructions on the line following the line

containing the

gosub

command.

Syntax

The

gosub

command has the following syntax:

gosub

<subroutine_name>

is the name of the subroutine.

Example

The following example shows a script using the

gosub

and

return

commands:

:main:

let arg = 1; gosub :SUBROUTINE:

echo “Return value: $return”

goto :EXIT:

:SUBROUTINE:

let return = ($arg*$arg) + $arg + 1

return

:EXIT:

1 2 ... 35 36 37 38 39 40 41 42 43 44 45 ... 115 116
