This document provides a listing of the COBOL source code for a callable routine that provide write access to a Record Sequential file. This program is included in the SimoCARD suite of programs.
Additional information about this program may be obtained by sending an e-mail to: helpdesk@simotime.com
The SimoPR80 program provides an easy to use, callable routine for accessing or writing records to a record sequential file with a maximum record length of 80-bytes.
The following is an example of how to initialize the pass area and then sequentially write records to the file.
move 'OPEN ' to PR80-FILE-REQUEST
move ZERO to PR80-FILE-STATUS
move SPACES to PR80-PASS-80
call 'SIMOPR80' using PR80-PASS-AREA
The following is an example of a call statement for the callable routine.
call 'SIMOPR80' using PR80-PASS-AREA
It is not necessary to do an explicit open of the file. The first call to the routine will open the file and write the first record. Subsequent calls will write a logical record in the file.

The following is a list of the parameters required when using the PR80-PASS-AREA to call the SimoGL80 routine.
| Parameter | Description | ||||||||
| PR80-PASS-REQUEST | This parameter must be provided by the calling program.
|
||||||||
| PR80-PASS-STATUS | A zero (0) value indicates a successful completion of the request. A non-zero value indicates the request could not be completed successfully. | ||||||||
| PR80-PASS-80 | This parameter will contain the logical record for a READ request. |
The following is the copy statement used in the LINKAGE section of the SIMOPR80 callable routine.

The following are environment variables used by the SimoPR80 write routine for record sequential files with a maximum record length of 80-bytes.
| Variable | Description |
| PUT080RS | This is the drive:directory\filename.ext for the input file. This
will map the DD name to the fully qualified PC file name. For
example: SET PUT080RS=C:\MYDIRECTORY\MYFILE.DAT |
