Table 1-2. Types of string constants (Continued)

Constant	Definition	Example
EBCDIC	EBCDIC constants are used for	IDEN	PREFIX='DJDE';
	value and string constants. They	TABLE	CONSTANT='ABCDE';
	must be preceded by the
	characters E apostrophe (E’) and	IDEN PREFIX=E'ABC!C4EFG'
	followed by an apostrophe
		is equivalent to the hexadecimal
	character (’). The EBCDIC string
		IDEN PREFIX=X'C1C2C3C4C5C6C7’
	type allows hexadecimal
	representation of characters to be
	embedded in a character string.
	This is done by preceding the
	hexadecimal representation of the
	character with an ! character.
	Each character represented in
	EBCDIC results in one byte. Each
	three character sequence
	representing a character
	hexadecimally results in one byte.
	NOTE: If no character type is
	specified, EBCDIC is the default.
Octal	Octal constants should be used	RECORD	CONSTANT=O'07070707'
	only as string constants because
	of the control program conversion
	process. Each octal character
	results in three bits.
	Each octal character pair is
	converted internally to an 8 bit
	octal character by prefixing two
	binary zeros. Thus, the arithmetic
	value of a multiple character octal
	constant may be difficult to
	determine, because each digit in
	the constant has been altered.
	An octal constant must be
	preceded immediately by the
	characters letter O apostrophe (O’)
	and immediately followed by the
	apostrophe (’) character.
