This is what I found on internet, Retrieve Call Stack (QWVRCSTK) API.
| Code: |
| PROCESS NOMONOPRC. * To compile: * CRTCBLMOD CALLSTACK * CRTPGM CALLSTACK BNDDIR(QC2LE) IDENTIFICATION DIVISION. PROGRAM-ID. CALLSTACK. DATA DIVISION. WORKING-STORAGE SECTION. COPY QUSEC OF QSYSINC-QCBLLESRC. COPY QWCATTR OF QSYSINC-QCBLLESRC. 01 Receiver. 05 Bytes-Returned PIC S9(9) BINARY. 05 Bytes-Available PIC S9(9) BINARY. 01 Memory-Pointer POINTER. 01 Stack-Pointer POINTER. 01 My-Name PIC X(10). LINKAGE SECTION. COPY QWVRCSTK OF QSYSINC-QCBLLESRC. PROCEDURE DIVISION. MAIN-LINE. MOVE 0 TO Bytes-Provided OF QUS-EC. PERFORM Get-Caller THRU Exit-Get-Caller. STOP RUN. Get-Caller. * Find out how much information is available * First initialize the Job Information structure MOVE LOW-VALUES TO QWC-JIDF0100. MOVE "*" TO JOB-NAME OF QWC-JIDF0100. MOVE SPACES TO USER-NAME OF QWC-JIDF0100. MOVE SPACES TO JOB-NUMBER OF QWC-JIDF0100. MOVE SPACES TO INT-JOB-ID OF QWC-JIDF0100. MOVE 1 TO THREAD-INDICATOR OF QWC-JIDF0100. * Then call the API CALL "QWVRCSTK" USING BY REFERENCE Receiver, BY CONTENT LENGTH OF Receiver, BY CONTENT "CSTK0100", BY REFERENCE QWC-JIDF0100, BY CONTENT "JIDF0100", BY REFERENCE QUS-EC. * Allocate enough memory for the information CALL LINKAGE PRC "malloc" USING BY VALUE Bytes-Available OF Receiver RETURNING Memory-Pointer. SET ADDRESS OF QWV-CSTK0100 TO Memory-Pointer. * Now get the information CALL "QWVRCSTK" USING BY REFERENCE QWV-CSTK0100, BY CONTENT Bytes-Available OF Receiver, BY CONTENT "CSTK0100", BY REFERENCE QWC-JIDF0100, BY CONTENT "JIDF0100", BY REFERENCE QUS-EC. * Not available for some reason? IF ENTRY-AVAILABLE OF QWV-CSTK0100 = 0 DISPLAY "Major problem accessing call stack" ELSE * Display the program name SET Stack-Pointer TO Memory-Pointer SET Stack-Pointer UP BY ENTRY-OFFSET OF QWV-CSTK0100 SET ADDRESS OF QWV-RCSTK-ENTRY TO Stack-Pointer MOVE PROGRAM-NAME OF QWV-RCSTK-ENTRY TO My-Name PERFORM TEST AFTER UNTIL PROGRAM-NAME OF QWV-RCSTK-ENTRY NOT EQUAL My-Name SET Stack-Pointer UP BY ENTRY-LENGTH OF QWV-RCSTK-ENTRY SET ADDRESS OF QWV-RCSTK-ENTRY TO Stack-Pointer END-PERFORM DISPLAY "My caller is: " PROGRAM-NAME OF QWV-RCSTK-ENTRY END-IF. * Now free the allocated memory CALL LINKAGE PRC "free" USING BY VALUE Memory-Pointer. Exit-Get-Caller. |
