Hi, Carl.

One option would be to modify caget to use a different separator.

Even better, I think, would be to modify caget to accept another command
line option allowing one to specify the separator.  (This could then be
included in a future EPICS release.)

If you don't want to change caget, you could use a different program, or
you could write your own small program using the CA library and write
out the values however you want.
