<expression

SwitchEnd
<expression 1> through <expression
n
> should be expressions that produce real
numbers.
Function: This command executes one of a series of processes based on the value of
<expression>.
Description
• This command executes the statement following the Case expression that matches the
Switch expression.
• If there is no matching Case expression, the statement following Default is executed. If
there is no Default specified, a non-match jumps to the statement following SwitchEnd.
• You can use a multi-statement command (:) in place of the carriage return to separate
statements.
• Switch~SwitchEnd can be exited using the Break command, Return command, or Goto
command.
Wait
Syntax: Wait
[<expression>]
Function: This command pauses program execution, and then restarts it after the number of
seconds specified by the expression passes.
Description
• If you do not specify any expression, program execution is paused until you tap the screen,
or press a key.
• The maximum valid specification for <expression> is 360 seconds (six minutes). Specifying
a value greater than 360 causes program execution to resume after 360 seconds,
regardless of the specified value.
• The ClassPad’s Auto Power Off function is disabled during a pause caused by the Wait
command.
• If the Auto Power Off trigger time is reached during the pause, program execution resumes.
