CHR

Syntax:

CHR( %Number) ==> $String

Description:

Given an integer in the range 0 to 255, returns a string with the

single character corresponding to that ASCII value.

Action:

Assign a string value to the variable specified.

Parameters:

%Number. A numeric value from 0 to 255.

Returns:

String value, as follows:

String Value Meaning

Empty The ASCII value specified was 0, or

outside the range 0 to 255

Single character The character represented by the

specified ASCII value

Notes:

Technically, ASCII values are only in the range of 0 to 128, but some

systems (including the MCC) use the ISO 8859 “Latin 1” or ANSI

character set, which contains values from 0 to 255. See Appendix A

ASCII Character Values for a complete list of characters and their

values.

Example:

%Num := 66

$Character := CHR(%Num)

// The variable $Character will contain the letter B.
