Technologies

Project is created with:

  • COBOL
  • JCL

Installation

  • Available z/OS COBOL compiler PTF

PSEUDO-RANDOM ORDER OF THE QUESTIONS # In Progress
Beautify code ### In Progress

Run the Project

  • First we need to compile it using default JCL for Enterprise COBOL
  • Then we check compile results and correct warnings or errors if exists or just send them here to the author (to fix the code)
  • Edit 'OPERQUIZ.JCL' and change it for our need
  • Options available to SET the proper MODE
//*            PLEASE CHOOSE ONLY ONE PARAMETER:
//* OPERATOR        FOR CONSOLE OPERATOR INTERACTION
//* BATCH           BATCH TO PRINT QUESTIONS AND ABCD ANSWERS PROPOSAL
//* C,ABCDA         TO PRINT THE CORRECT ANSWERS SUMMARY
//*   -----  , WHERE ABCDA IS A USER ANSWER FOR 5 QUESTIONS
//*
//          SET USERP1='OPERATOR'
//**        SET USERP1='BATCH'
//**        SET USERP1='C,-----'
//STEP1 EXEC PGM=OPERQUIZ,PARM='&USERP1'

Default setting is an operator mode and the rest of available options is commented:

//          SET USERP1='OPERATOR'

For batch mode PRINT QUESTIONS we need to comment and uncoment JCL code as below:

//**      SET USERP1='OPERATOR'
//        SET USERP1='BATCH'

For batch mode CHECK USER ANSWERS AND PRINT SUMMARY we need to input 5 letters from range A to D to JCL code in place of '-----':

//        SET USERP1='C,AABBC'

From TSO: SUBMIT 'USERID.OPERQUIZ.JCL'

TODO

  • Branch in V3.0.0 will implement some PSEUDO-RANDOM order of the questions for console mode
