You must format the source catalogs so the catalog intrinsics can access them. GENCAT formatted message files are binary and cannot be edited. Formatting compacts the files and creates a directory, which saves disc space and reduces access time. As shown in Title not available GENCAT creates a formatted catalog from a source file.

[Formatting a Source File With GENCAT]

During the formatting process, GENCAT verifies that:

  • All directives are legal and used correctly.

  • Set numbers are in ascending order.

  • Set numbers are greater than 0 and less than 256.

  • Message numbers are in ascending order within each set.

  • Message numbers are greater than 0 and less than 32,767.

  • Continuation and concatenation characters are correct.

  • Parameter substitution characters are used correctly.

The dialog listed below is an example of formatting a source catalog:

     :RUN GENCAT.PUB.SYS

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

     >>FORMAT

     TOTAL NUMBER OF SET FORMATTED = 3
     TOTAL NUMBER OF MESSAGES FORMATTED = 8
