CHAR Function

Converts a decimal value to the corresponding ASCII or multi-byte character.

Syntax

CHAR(charValue{,charSize})

Syntax elements

charValue An expression that evaluates to an integer value, specifying the decimal value of the required character.

charSize Optional. A positive integer in the range 1 to 6, specifying the size of the character (default, 1). This parameter is intended for future use with multi-byte characters.

Return value

The character with the code charValue.

Comments

Reality does not currently support multi-byte characters; however, CHAR may be used for decimal to binary conversions, where charSize is the number f bytes in the binary field generated.

If value is greater than 256^charSize, it is divided by 256^charSize and the remainder is used.

CHAR is the inverse of the SEQ function.

Examples

Assigns the string value of a value mark to variable VM:

VM = CHAR(253)

Assigns the ASCII string value for a subvalue mark to variable SVM:

X = 252
SVM = CHAR(X)
