Subparameter definition

access-code: Specifies an accessibility code. The access code is 1 through 8 characters. In ISO/ANSI/FIPS Version 3 the first character must be an upper case letter from A through Z. In ISO/ANSI Version 4 the first character must be an upper case letter from A to Z, number from 0 to 9, or one of the special characters ! * " % ' ( ) + , - . / : ; < = > ? and _ .
Enclose the ACCODE in apostrophes if you specify special characters. For example, ACCODE='AB/CD'. Specify two apostrophes if you include an apostrophe as a special character. For example, to specify DAY'SEND, use ACCODE='DAY''SEND'.

Note: ISO/ANSI/FIPS Version 3 and ISO/ANSI Version 4 use only the first character as the accessibility code; the installation can use the other seven characters. If the first character is other than those allowed, the installation does not give control to the file-access exit routine.
