EFS restrictions when an EFS program is in effect

In addition to the previous items, the following restrictions apply to control statement preparation for an EFS program.

• Non-DFSORT operation definers can be up to 8 bytes long.
• An operation definer with no operands is allowed only if:
  • It is supplied through SYSIN, SORTCNTL, or DFSPARM.
  • It is the only operation definer on a line; column 72 must contain a blank.
