The Level Identifiers used for Level Check Errors are only
checked when a file is opened. Your CL program will get a
level check error if it opens the file. For example, using
the RCVF command to read through the file would get the
level check error. It will get CPF4131: Level Check On File
XXX in Library YYY with member ZZZ. Your CL program could
monitor for that error to allow you to gracefully exit the
prgram.

If you are doing an OVRDBF this will not cause a level
check because all you are doing is pointing to another
file. The program opening the file will generate the Level
Check error
