Bill, 

You can use the substitution parameters to execute OVRDBF from within the OCL. 
The logical file DDS however, must contain the actual name(s) of the physical 
files. You could generate the LF DDS on the fly with the correct names with a 
small RPG program. If you build the files in a library like QTEMP that is 
unique to the job, you wouldn't even need the OVRDBF, as you could always use 
the same logical file name. Other possibilities: You might use CRTDUPOBJ to 
duplicate the physical and logical files from empty "model" files and then 
rename the physicals before saving them. You could also use multiple member 
physical files. Give the members the unique names and add a corresponding 
logical file member. You can specify the PF members in the CRTLF command.
