ANTNUM returns the antenna number of a named antenna. You can use ANTNUM to
set antenna adverbs for AIPS tasks without having to consult antenna table
listings as in the following example.

TASK = 'CALIB'
GETN 3
SUBARRAY = 1
ANTENNAS = ANTNUM('PT'), ANTNUM('LA'), ANTNUM('FD')
REFANT   = ANTNUM('PT')

To have ANTNUM print an antenna number to the terminal type, for SC as
an example:
TYPE ANTNUM('SC')

ANTNUM will not work on files without antenna (AN) tables.
