Cycles: Setting parameters for user cycles

Function
You can use the cov.com and uc.com files to parameterize your own cycles.
The cov.com file is included with the standard cycles at delivery and is to be expanded
accordingly. The uc.com file is to be created by the user.
Both files are to be loaded in the passive file system in the "User cycles" directory (or must
be given the appropriate path specification):
;$PATH=/_N_CUS_DIR
in the program.
Files and paths
