Input/output and calling DIRCONV

Output from DIRCONV is directed to SYSOUT.

DIRCONV can only process directory files. Other file types are rejected. The directory files for input and output must not be identical.

DIRCONV is called with:

/START-DIRCONV

or

/START-EXECUTABLE-PROGRAM $DIRCONV

DIRCONV then checks the specified input file to ascertain whether it is a directory file. If it is not, the run is terminated and the following message is issued:

FILE EMPTY OR NOT IN CORRECT FORMAT

Any errors occurring during a system function call or data access will cause DIRCONV to terminate abnormally. An appropriate message to be output.

Large directory files should always be reorganized after a DIRCONV run.
