Tips for Writing Valid JCL:

1. Always start JCL statements with '//' (except for comments which start with '//*')
2. Ensure each line doesn't exceed 72 characters
3. Use continuation character ',' in column 71 if a statement needs to continue to the next line
4. Double-check spellings of keywords and parameters
5. Verify that all required DD statements (e.g., SYSPRINT, SYSUT1, SYSUT2) are present for each step
6. SYSIN data (
