See PBP Manual Appendix B

DEFINE OSC 4 ' (for a 4MHz Clock)

Thanks for the reply.
It means, I am in the right place, where Microcode Studio is discussed.

Another question:
What I had understood from MicroCode Studio's Help files, that all of the commands of PBP are available. But the definition of OSC frequency is not mentioned in the help. It means, I have to read the PBP manuals also?

Always better to read the manual than the Help file of a third party. BUT if you type DEFINE in MCS and press f1... you should see all define available.
