Cheat Sheet
- 88-Level Condition Names -
In the COBOL Data Division the 88 level defines named boolean conditions for fields, such as
88 AVAILABLE-FLAG VALUE 'Y'
. They allow you to write clearer IF statements likeIF AVAILABLE-FLAG
instead of checking literal values. A handy mnemonic is that "88" looks like two switches, each representing TRUE or FALSE. - COBOL File Handling Verbs -
Master the OPEN, READ, WRITE, and CLOSE verbs to manage sequential and indexed files efficiently. Always check the FILE-STATUS 02-level status code to handle end-of-file conditions - e.g.,
READ IN-FILE AT END MOVE 'Y' TO EOF-FLAG
. Remember the sequence acronym "ORWC" (Orange Rabbits Wear Caps) to lock in your workflow order. - JCL DD Statement Essentials -
The DD statement defines dataset attributes like
DSN
,DISP
,UNIT
, andDCB
for each file. For example://INFILE DD DSN=MY.DATA.FILE,DISP=SHR,UNIT=SYSDA
. Familiarity with DISP parameters (NEW, OLD, SHR) is crucial for safe dataset allocation. - Batch JCL Job Structure -
A basic JCL job starts with a JOB card, followed by one or more EXEC steps and their DD statements. Example skeleton:
//MYJOB JOB …
. Remember JOB → EXEC → DD to build every batch workflow correctly in your COBOL JCL Quiz practice.
//STEP1 EXEC PGM=MYPROG
//STEPLIB DD DSN=MY.LOADLIB,DISP=SHR - JCL Return Codes & Conditional Processing -
JCL uses the return code (RC) from each step to determine success or failure; RC=0 usually means success. Use JCL IF/THEN/ELSE constructs to branch - e.g.,
//IF (STEP1.RC = 0) THEN
. Tracking RC values in SYSOUT helps you debug and refine your COBOL JCL Quiz solutions with confidence.
