CA Dynam for VSE User Guide

Using Other Software with CA Dynam/FI
With Sort Packages
CA Dynam/FI relies upon the use of logical IOCS for file processing. By
trapping and modifying LIOCS requests, CA Dynam/FI is able to function. As a
rule, sort packages do not use LIOCS for processing and generally use
skeleton DTFs or a DTFPH. This incompatibility between methods of operation
makes it impossible for CA Dynam/FI to override the parameters specified for
the sort.
The record format and file structure information in the sort parameter
statements is used by the sort product internally for handling the data and
sorting the records. As a result, the label information and parameter values
specified for the sort product must reflect the true characteristics of the files to
be used (i.e., the file characteristics after modification by CA Dynam/FI).
The CA SORT system, however, contains an interface to CA Dynam/FI.
CA SORT
CA SORT, contains an interface to CA Dynam/FI. This interface allows CA
Dynam/FI to pass the necessary information about the true structure and
attributes of the applicable files to CA SORT. The block size, record length, and
record format as specified in the sort parameter statements are overridden by
the CA SORT interface using internal communications.
Limited support for concatenation of input files read by CA SORT is provided
by the CA Dynam/FI - CA SORT interface. CA Dynam/FI will pass the number
of input files to be concatenated to CA SORT, and subsequently perform label
and OPEN/CLOSE processing for the concatenated files. As CA SORT uses
physical IOCs, all concatenated input files must have the same physical and
logical characteristics.
When you use CA SORT with CA Dynam/FI, be sure that CA SORT rules and
conventions are followed. These include such things as:
• All input files must have the same record format.
• All input files must have the same record length and block length.
• The record format may not change during the SORT from input to output
(unless by user exit).
• The logical record lengths must be the same for all SORTIN and SORTOUT
files when fixed-length records are used.
