Packed-Decimal or Computational-3 (COMP-3) MOVE TO WS-AMOUNT ====> 4 bytes instead of 7. Significant storage saving. On the AS/400 numeric zoned decimal field is –converted to packed decimal format – Arithmetic is performed –converted back to zoned decimal format.

Data Division –Choose meaningful names –Prefix all data names within the same FD or 01 with tow or three characters unique to the FD –Begin all PICTURE clauses in the same column –Choose one form of PICTURE clause –Indent successive level numbers under an 01 consistently –Avoid 77-level entries Coding Standards Procedure Division –Develop functional paragraphs –Sequence paragraph names –Avoid Commas –Use scope terminators –Indent Both Divisions –Space attractively –Avoid constants –Don’t overcomment
