Creating a New Source File

Title not available shows how the new source file is created by merging the old source with the maintenance file. A collision file may be created at this time. Collision files are described in the next section.

Figure 4-3 Creating a New Source

The dialog listed below is an example of merging source and maintenance files. Note that the method of merging you specify depends on the type of maintenance file you created. To use GENCAT to modify your source catalog, enter:

     :RUN GENCAT.PUB.SYS 

     HP32414A.02.01 GENCAT/3000 (C) HEWLETT-PACKARD., 1983 

      ENTER INDEX OF DESIRED FUNCTION 

      0.  EXT. 
      1.  HELP. 
      2.  MODIFY SOURCE CATALOG. 
      3.  FORMAT SOURCE INTO FORMATTED CATALOG. 
      4.  EXPAND FORMATTED CATALOG INTO SOURCE. 

     >>2 

     ENTER NAME OF CATALOG SOURCE FILE TO BE MODIFIED 

     >>SOURCE 

     ENTER NAME OF MAINTENANCE FILE 

     >>MAINT 

     ENTER INDEX OF MERGE TYPE 

     0.  DO NOT MERGE. 
     1.  HELP. 
     2.  BY LINE NUMBER. 
     3.  BY SET/MESSAGE NUMBER. 

     >>2     or >>3 

Entering an "0" or Return aborts the maintenance function and returns to the main menu.

You have the option of saving all the modifications resulting from the merge in a collision file.

     SAVE COLLISIONS?  ENTER "YES" OR "NO" 

     >>YES 

     ENTER NAME OF COLLISION FILE 

     >>COLISION 

If the name of an existing file is entered, the prompt is repeated. A Return continues the merging without saving the collisions.

GENCAT merges the source and maintenance files into a temporary file, and will prompt for the name of a permanent file:

     ENTER NAME OF NEW SOURCE CATALOG FILE 

     >>NEWSOURC 

This prompt is repeated until a unique file name or a Return is entered. The temporary file is copied to the new permanent file. If a Return is entered, the merging is aborted.

After a new source is created, it must be formatted before it can be accessed. Formatting a source catalog is discussed in Chapter 3.
