$CREATE

The Create service constructs a new file according to the attributes you specify in the FAB. If any XABs are chained to the FAB, then the characteristics described in the XABs are applied to the file. This service performs implicit Open and Display services.

Format

SYS$CREATE fab [,[err] [,suc]]

RETURNS

OpenVMS usage: cond_value

type: longword

access: write only

mechanism: by value

The value is returned in symbolic offset FAB$L_STS. Symbolic offset FAB$L_STV may contain additional status information.

Arguments

fab

OpenVMS usage: fab

type: longword (unsigned)

access: modify

mechanism: by reference

FAB control block whose contents are to be used as indirect arguments for the Create service call. The fab argument is the address of the FAB control block.
err

OpenVMS usage: ast_procedure

type: procedure value

access: call without stack unwinding

mechanism: by reference

AST-level error completion routine that the service invokes if the operation is unsuccessful. The err argument is the address of the entry mask of this user-written completion routine.
suc

OpenVMS usage: ast_procedure

type: procedure value

access: call without stack unwinding

mechanism: by reference

AST-level success completion routine that the service invokes if the operation is successful. The suc argument is the address of the entry mask of this user-written completion routine.

Description

The Create service first uses the information from the specified FAB. If an allocation control XAB is present, however, its allocation quantity (XAB$L_ALQ), allocation options (XAB$B_AOP, only for the XAB$V_CTG and XAB$V_CBT options), bucket size (XAB$B_BKZ), and default extension quantity (XAB$W_DEQ) fields are used instead of the corresponding fields of the FAB. When either key definition or allocation XABs are present, they can be grouped in any order. If a name block (NAM) or long name block (NAML) is also connected to the FAB, RMS fills in its fields with information about the created file. The Create service leaves the file opened.
When a search list logical name is used, the file is placed in the first resultant search list file specification unless the create-if (FAB$V_CIF) option is specified. If you select the FAB$V_CIF option, RMS searches all search list file specifications to locate the file. If it finds the file, RMS opens it rather than create a new file. If RMS does not find the file, it creates a new file using the first resultant search list file specification.
You do not have to explicitly specify the FAB$V_PUT option when invoking a Create service because write is the default access mode when you create a file.
Table RMS-5 lists the control block fields read as input by the Create service. For additional information on the fields accessed by this service, see Chapter 4.

Note
If you specify this option as input to the Create service, RMS overwrites the tape beginning with the first file.
