    Well, the "ts" command says that they are different versions ...
    /com/lcm has a time-stamp of 1987/03/09 and the /systest/ssr_util/lcm
    file has a time-stamp of 1986/10/30, which makes /com/lcm the newer
    version. If I had to guess at the differences, I would bet that
    /com/lcm knows how to handle the newer color screen types.

No, it doesn't need to change, since it just calls gpr_$set_color_map(),
which takes care of the differences for you.  You could write your
own lcm using this call if you really want.

According to nm, the difference is that the new one makes these calls
which the old one didn't:

error_$print_format
help_$args
pgm_$exit
pgm_$set_severity

And, the old one used to call pfm_$error_trap().

So, I would say that the newer one has been fixed up to be a little more
user-friendly, but is functionally the same.
