Purpose - to create a reference file named "serfil" of station ids and
ssns that is then read by program compgb.

The user is prompted for the filename of a Blue Book B-file. The program
reads the B-file *25* record ssns and station ids. Cr8ser creates an
output file named "serfil" consisting of the unique station ids and
their corresponding ssns. The program retains the last ssn found for
each unique station id. The output file overwrites any existing file
named "serfil". No error messages are generated from cr8ser. This file
is then read by program compgb to serve as a reference file of station
ids and their ssns. The user enters the filename "serfil" when compgb
prompts the user for the name of the station file.

The format of the "serfil" file is: 

    cc 1- 4 four character station id
    cc 5- 7 blank
    cc 8-11 station serial number

Version 1.3 allows the user to specify the "serfil" output filename.
