How TEMPLI Merges Template Files

TEMPLI follows certain rules when it merges separate template object files into

resident and nonresident template files.

Check for Duplicate Template Keys

A template key appears in each record of the key-sequenced template object file that

the Template Compiler, TEMPL, produces.

When TEMPLI merges template object files, it checks each template’s template key—

consisting of a subsystem ID, a token code, a token value, and a template type—for

duplicates. If TEMPLI finds a duplicate template key, it places the latest template in the

template files it produces. That is, it uses the template appearing in the template object

file specified latest on the TEMPLI command lines or in the SYSGEN configuration file.

There are no duplicate template keys within the same template object file because

TEMPL allows only one occurrence of each template key.

Preserving Abbreviated Subsystem ID Specifications

When there is a duplicate template key, TEMPLI normally uses the template in the file

specified latest on the TEMPLI command line or in the SYSGEN configuration file.

However, to preserve an abbreviated subsystem ID specification, if two templates are

derived from an SSNAME statement, and only one template contains a subsystem ID

abbreviation, TEMPLI uses the template with the subsystem ID abbreviation. Whether

this template is in the file specified latest does not matter in this case.

Check for Duplicate Abbreviated Subsystem IDs

While merging files, TEMPLI also checks for duplicate subsystem ID abbreviations

within the files it is merging. If TEMPLI finds the same abbreviated subsystem ID for

two different applications, it returns warning 42.

Merging Template Object Files With Nonresident Template Files

TEMPLI can merge template object files with nonresident template files. This is useful

if you merge a new template object file with an existing nonresident template file and

then use COUP to install the new resident and nonresident template files. However, be

sure to specify the new template object file last. Then, if older templates in the

nonresident template file have the same template key as newer templates, the newer

templates appear in the files instead of the old templates.

Note. The nonresident template file size cannot exceed 400 MB.
