This subroutine generates the remaining octet map for a given Data Representation Template, if required\&. Some Templates can vary depending on data values given in an earlier part of the Template, and it is necessary to know some of the earlier entry values to generate the full octet map of the Template\&.

.PP
This subroutine returns DRS template information for a specified Data Representation Template 5\&.NN\&. The number of entries in the template is returned along with a map of the number of octets occupied by each entry\&. Also, a flag is returned to indicate whether the template would need to be extended\&.
