// DESCRIPTION: This program shows a customer master search *
// program using workstn subfile processing. *
// This program prompts the user for the customer*
// name and uses it to position the cusmstl3 *
// file by the setll operation. Then it displays *
// the records using subfiles. *
// To fill another page, press the rollup key. *
// To display customer detail, enter 'X' beside *
// that customer and press enter. *
// To quit the program, press PF3. *

/end-freeThe file description specifications identify the disk file to be searched and the display device file to be used (SNAMMENU). The SFILE keyword for the WORKSTN file identifies the record format (SUBFILE) to be used as a subfile. The relative-record-number field (RECNUM) specifies which record within the subfile is being accessed.
The program displays the PROMPT record format and waits for the workstation user's response. F3 sets on indicator 03, which controls the end of the program. The name (NAME) is used as the key to position the CUSMSTL3 file by the SETLL operation. Notice that the record format name CUSREC is used in the SETLL operation instead of the file name CUSMSTL3.
The SFLPRC subroutine handles the processing for the subfile: clearing, filling, and displaying. The subfile is prepared for additional requests in subroutine SFLCLR. If indicator 55 is on, no action occurs on the display, but the main storage area for the subfile records is cleared. The SFLFIL routine fills the subfile with records. A record is read from the CUSMSTL3 file, the record count (RECNUM) is incremented, and the record is written to the subfile. This subroutine is repeated until either the subfile is full (indicator 21 on the WRITE operation) or end of file occurs on the CUSMSTL3 file (indicator 71 on the READ operation). When the subfile is full or end of file occurs, the subfile is written to the display by the EXFMT operation by the subfile-control record control format. The user reviews the display and decides:
In Figure 217, the user responds to the initial prompt by entering a customer name.
22:35:26 CUSTOMER SEARCH & INQUIRY BY NAME 9/30/94
Enter Search Name JUDAH GOULD
ENTER - Continue F3 - End Job
The user requests more information by entering an X as shown in Figure 218.
22:35:43 CUSTOMER SEARCH & INQUIRY BY NAME 9/30/94 Search Name JUDAH GOULD Select "X" Customer Name Number Zip Code X JUDAH GOULD 00012 70068 JUDAH GOULD 00209 31088 ENTER - Continue F3 - End Job F4 - Restart Name
The detailed information for the customer selected is shown in Figure 219. At this point the user selects the appropriate function key to continue or end the inquiry.
