clipper dos program not able to access its files although they do exist

I installed dosemu 1.4 on VectorLinux 6.0 compatible with Slackware
12.1. I can start my DOSProgram by issuing command:
dosemu /home/path/program.exe
but when program starts it cannot find its cdx and dbf files although
they are there.
ANy hints?
Do I need to map that location somehow? Permissions are OK.

Thanks,

Vedran
