F$IDENTIFIER() converts an alphanumeric identifier to its integer equivalent, or converts an integer identifier to its alphanumeric equivalent. An identifier is a name or number that identifies a user or a category of users. The system uses identifiers to determine a user's access to a resource.
Format
F$IDENTIFIER(identifier,conversion-type)
Arguments
identifier
Specifies the identifier to be converted. Specify the identifier as an integer expression if you are converting an integer to a name. Specify the identifier as a character string expression if you are converting a name to an integer.
Any identifier holding the Name Hidden attribute will cause the F$IDENTIFIER to return an error when you do not hold the identifier in question or do not have access to the rights database. For further information on the attribute, see the VSI OpenVMS Guide to System Security.
conversion-type
- "NAME_TO_NUMBER": if the identifier argument is alphanumeric
- "NUMBER_TO_NAME": if the identifier argument is numeric
Examples
$ UIC_INT= F$IDENTIFIER("SLOANE","NAME_TO_NUMBER")
$ SHOW SYMBOL UIC_INT
UIC_INT = 15728665 Hex = 00F00019 Octal = 00074000031
$ UIC = F$FAO("!%U",UIC_INT)
$ SHOW SYMBOL UIC
UIC = [360,031]
$ UIC_INT = (%O31 + (%X10000 * %O360)) $ UIC_NAME = F$IDENTIFIER(UIC_INT,"NUMBER_TO_NAME") $ SHOW SYMBOL UIC_NAME UIC_NAME = "ODONNELL"
