Character Processing Rules (CPRL)
Procedures
This section describes CPRL procedures that a COBOL program can call to process
these collation objects:
•
SQL collation—An SQL/MP object with file code 941 generated
by the CREATE COLLATION statement
•
Collation object—A Guardian file with file code 199 generated by the NLCP
collation compiler ($system.system.NLCPCOMP)
Table 11-1 summarizes the CPRL procedures. These procedures are alphabetically
described in detail on subsequent pages in this section.
