# Subroutine SRPCRT($NAME,$NUM1,$NUM2)
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# Perl subroutine designed to generate coordinates of the source and
# receiver points for given configuration parameters, perform two-point
# ray tracing, and convert unformatted output into a simple formatted
# file.
#
# Input:
#     $NAME...Prefix of data files (name of the job).  Should not exceed
#             5 characters under MS-DOS.  $NAME, $NUM1 and $NUM2
#             together should not exceed 8 characters under MS-DOS.
#     $NUM1...Integer configuration parameter.
#     $NUM2...Optional second configuration parameter.
#
# No output.
#
# Executable programs required:
#     srp, crt, crtpts
# Input files:
#     $NAMEsrp.dat... Input file for the 'srp' program to generate
#             source and receiver files for given configuration
#             parameters.  The receiver file must be named
#             $NAME-rec.out.  Source and receiver names will be
#             prefixed with $NUM1-.
#     $NAMEcrt.dat... Input file for the 'crt' program.
# Output files:
#     $NAME$NUM1$NUM2.out... File containing travel times, slowness
#             vectors and amplitudes (in R.C.C.S.) at
#             the receivers.
#     $NAMEscr.out... Collected screen output of programs 'srp',
#             'crt', and 'crtpts' (written in an append mode).
