Syntax rules for the control statements

You must use the correct syntax when you code the CNTLCRDS and the PAGECNTL control statements for the Playback utility.

  • Control statement records are 80 byte fixed length.
  • Comment statements can be indicated with an asterisk (*) in column 1.
  • Blank records are ignored.
  • Control statements keywords are coded within the boundaries of columns 1 through 72.
  • Keywords can start in any column.
  • Keywords can be in any order.
  • There can be no intervening blanks between keywords indicating a data value and the value itself.
  • Multiple keywords are either:
    • Separated by one or more blanks.
    • Specified on multiple control statement records.
  • Keywords for which multiple occurrences are allowed must have each occurrence specified on a separate control statement record.
  • Individual keywords and their associated values cannot span or be continued on multiple control statement records.
  • Keywords must be in upper case.
  • For PAGECNTL, all control statements are optional. If no control statements are supplied, Playback treats each display as a single page screen.
