Model File Word Replacer

Information Exchange Group, Inc.

Each LINC platform has its own set of reserved words dictated by the underlying database and application language software. When transporting production LINC system specifications from one platform to another, some names, which were acceptable on the host platform, become unusable on the target platform.

Although LDA can help identify the reserved words, some case extract models will not load properly into LDA due to naming conflicts.

The challenge is then to replace words in the model file intelligently and within usage context. REPLACER reads a parameter file of words and replacements and applies them throughout a model consistently and in proper context.

The parameter file is a plain text file where each record describes a target word and its replacements in "comma-quote" delimited format. The sequence of entries in each record is:

1. The "Target" word to replace

2. The replacement word if found as an ISPEC data item name

3. The replacement word if found as a Global Logic name

4. The replacement word if found as an ISPEC name

5. The replacement word if found as a Report name

6. The replacement word if found as an SD or GSD

Empty (null) replacement words signify no replacement is to take place for that type of word. Replacement words cannot be longer than the target as this could cause line overflow in logic. The target word must not be qualified.

REPLACER provides an audit of all replacements and summarizes them by target and replacement type. A special case of the replacement word being "*****" for an ISPEC data name causes the word to be shown in the audit, but not replaced.

Reserved words include and other business-like words:

name

address

state

Naming conflicts:

A Report name being the same as a Global SD.

Parameter File

"NAME","NAIM"," "," "," ","SNAM"

The example instructs REPLACER to replace all ISPEC definitions of NAME and all their logic and Report frame paint references to NAIM, and all SD and GSD definitions of NAME and their logic references to SNAM.

This text file can also be maintained by Replacer itself.

*****

This is useful when determining all locations in the model where certain words are used, such as "START", "CALL", or "GLB.DESTINATION.".. This can produce a cross reference of where LINC verbs are used. When listing a LINC verb the semi-colon ";" is not entered.

"CALL","*****"," "," "," ",""
