Specifies the name of the current Proc-file.

Syntax

   P[ROC-FILE]= filename [,n]

For example: 

   >PROC-FILE  =FILEP,50

Where filename = FILEP and n = 50

Parameters

filename

is the name of an MPE ASCII file. The file may reside in any group or account, as long as you are allowed read and lock access to it through the MPE file security. If you do not have read and lock access a file system error 93, (FS-93) security violation, will occur. To specify a file that is not local to your group and account, you must use a fully-qualified file name in the form: file.group.account. For example, SPEC.PUB.SYS is a file named SPEC in the PUB group in the SYS account.

n

is the number of records in the file. The file can be from 5 to 400 records in length depending upon the number and length of procedures to be stored. (The default value is 126.) Each procedure is stored on a record boundary, and occupies one or more records. If n is specified for an existing file, it is ignored.

Discussion

Procedures are stored in the Proc-file. Before using any of the QUERY procedure commands, you must specify the name of the Proc-file. This definition stays in effect until changed with the PROC-FILE = or DEFINE command or until execution terminates.

If the file name does not exist, QUERY issues a message and opens and saves a disc file of size n with the specified file name using a file code of 1070. Once a Proc-file has been declared, QUERY always uses that file when executing any of the commands listed in the following table. If you have not specified the Proc-file before entering one of these commands, QUERY prints an error message.

The following table shows the commands which are used to modify procedures and those which are used to execute procedures. All of these commands operate on the current Proc-file.

MODIFICATIONEXECUTION

ALTER CREATE DESTROY DISPLAY RENAME

FIND procedure JOIN procedure MULTIFIND procedure REPORT procedure SUBSET procedure UPDATE procedure

Examples

Example 1

In the following example DISPLAY LIST is used to list the procedures in the current Proc-file. MANPROC contains five procedures.

>PROC-FILE =MANPROC >DISPLAY LIST FIND1 FIND2 UPD1 REP4 REP5

Example 2

You can create a Proc-file with the PROC-FILE = command. If you do not specify the number of records QUERY creates a file with 126 records. 

      >PROC-FILE  =PROCX

      FILE DOES NOT EXIST, BEING CREATED
