CALC records

[lewis@csg.lbl.gov (Steve Lewis)]

I have recently been using CALC records for some moderately complex
calculations.  I found the use of "NOT" for unary minus a waste of
character space and non-obvious.  Would anyone support either the
additional work to detect "-" as unary minus by context, or allowing,
say, "@" to be a synonym?

I notice that "^" and "**" are synonyms for binary exponentiation.  It
would seem more reasonable to allow "^" as a synomym for bit-wise
"XOR", since that is the standard for C and "XOR" is another space-waster.
Besides,  "**" is only two characters in length and is standard in
FORTRAN.

How about "LN" as a synonym for "LOGE" (natural log)?  It is shorter,
and is common mathematical practice.

My motivation here is to reduce character usage, since the field length
is quite limited, and to increase readability.  (Only the re-assignment
of "^" would affect existing records.)
