Data conversion parameters

The >D, >I and >N commands, the equivalent <PF4>, <PF5>, and <PF6> keys, and the more complex GH and RH commands all expect to find data conversion parameters on line 3: as five comma-separated fields (see Table 71). These conversion parameters are retained by DK1TDRVC for subsequent data conversion operations.

Units of all numeric fields are bytes. Formats are those used in tablesONLINE/CICS Views. See the tablesONLINE/CICS User’s Guide for details. The most common conversion is between character (X) and hexadecimal (Y), but any conversion possible in tablesONLINE/CICS is possible here.

Like tablesONLINE/CICS, DK1TDRVC is designed to trap most errors in format instructions or in the data on which they operate and generate messages.
