Overview
There are seven different file handler utilities. Two of these work with
all recognized file types:
fhconvert converts an existing file into a different type of
file
fhvalidate inspects a file for consistency
The other five utilities work only with indexed files:
fhcreate builds an empty indexed file
fhedit adds and deletes indices
fhinfo accesses file and index information
fhrebuild reindexes a corrupt file
fhreorg reorganizes an indexed file
This chapter shows you how to invoke the utilities and gives the type of
files supported by the File Handler utilities and the default file type
parameters, the default indexed block size of the utilities, the use of
keys in indexed files, and error conditions which may arise when using
the utilities. The utilities themselves are detailed in this chapter in
their own sections and a section has been dedicated to the File Handler
utilities demonstration programs supplied with this COBOL system, which
show you how to use each utility.
