Value constants
Value constants are constants that have arithmetic values. They should be expressed as
decimal numbers. They may be expressed as hexadecimal values, octal values, or even
character values, but these expressions are not recommended. Decimal constants may be
signed and in some cases may have fractional digits, for example:
PDE BEGIN=(1.1, .37);
BLOCK LENGTH=1320;
RECORD LENGTH=132;
String constants
String constants are normally used to specify strings of characters or to reference identifier
parameters. String constants may be expressed as any of the following:
• Keyword
• Identifier
• Hexadecimal
• Character
• ASCII
• EBCDIC
Keyword
Keywords are terms that direct the system to perform specific predetermined activities.
Keywords always consist of the same characters and do not vary. For example:
OUTPUT
YES and NONE are keywords.
8
DUPLEX=YES,
FORMS=NONE;
