# case statement

The case statement delineates a conditional
case construct.

## Syntax

```
begin case
 case logical.exp
 {statement{s}}
 .
 case logical.exp
 {statement{s}}
 .
 .
end case
```

## Description

Only the statements following
the first true case statement are executed. Upon
completion of these statements, program execution continues immediately
following the end case statement.

If all case statements evaluate false, program execution is continued
at the first statement after the end case.

A case 1 statement always evaluates true and is
used as the last case statement to be processed
only when all previous case statements evaluate
to false.

The case statement is equivalent
to nested if expressions as follows:

```
if logical.exp then
 {statement{s}}
 end else
 if logical.exp then
 {statement{s}}
 end
end
```
The statements between case statements
are executed if the expression associated with the case statement evaluates to true. If the expression evaluates to false,
the statements are not executed.

## Example(s)

```
begin case
* check for operators response
case response = "p"
 printer on
case response = "s"
 echo off
case 1
 crt "response must be ’p’ or ’s’"
end case
```
In this example, if the response is `p`, the printer on statement is issued. The program
would then branch to the next statement after end case. The case 1 is executed only if response is neither `p` nor `s`.
