Control-D can retrieve output in one of two ways:
Control-D output retrieval is extremely flexible, allowing the exact requirements of each user to be met.
Control-D has the ability to decollate information that resides on a 32K column page.
The WHEN line and column range parameters specify the area on a report page in which the identifying character string is to be located.
The special line range 999-999 is used to describe decollation of the entire page as a stream of data. It is usually used when decollating a sysout in Page Mode. When a sysout is produced in Page Mode (as opposed to Line Mode), there are no real line numbers in the report (usually used for graphics). There is no way to check for line range. The search for the string is performed on the entire page.
The special column number 999 is used to describe decollation of an entire row. The string search is performed on the entire row (useful for AFP format lines that are longer than 998 characters).
Each report (on the JCL DD statement level) can be defined for retrieval by either of the two methods mentioned above. One job can produce two reports, one report being retrieved from the system spool and the other directly from CDAM.
