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.
