ATTACHMENT B

Sfep 3:
Export the data from the newly created business class of service lables above
as ASCII (TXT extension) using the Utility I Export facility. For simplicity,
use the table name as the export file name. Paradox will attach the .TXT extension.
Step 4:
~
Determine the Nth circuit which should be pulled from each export file by
dividing the number of circuits per file by the target sample size:
Example: Text File Name Circuits* Sample Size Every Nth
7 GSB.TXT (small bus
1 #'
use # of records as identiCied in PARADOX.
Step 5:
Run the sample selection program for each business circuit text file. Fust run QBASIC
(usually in the DOS subdirectory). Then select File Open and type SAMPLE.BAS.
Then select Run. The program will ask for an input file - type the name of the
business text file. The program will then ask for an ouput file - give the program
a file name which will represent the total business sample. The extension should
be "TXT". Finally, the program will ask you to type the number of the Nth circuit
which you would like to include in the sample as well as the random start.
Repeat the process for each business text file using the same ouput file name.
The program will append the contents of the output file each t he the program
run. Thus, the output file will include the sample selections from each CRIS extract
C. Combining Residence &Business Samples into One File:
Step I:
Sfep 2:
Run the sample selection program using the text files (one for residence and one
for business) created in steps A and B as input files. Name the output file
"XXsample.bt", where XX represents the state abbreviation. In response to the
Nth Circuit and Random Start prompts, fYPe a 1 for each. The program will
write each line of the input file to the output file, appending the output file for
the second execution. Hence, the output file will contain the contents of both
input files. (run the SAMPLEBAS program once for residence and once for
business; change the input file but keep the output file name consistent)
Convert the sample selection ouput fie created in step 1 into a format which
LMOS can understand. While in QBASIC, select File Open and type CONVERT.BAS.
Then select run. The program will ask for an input file - type the name of the
sample selection output file. The program will then ask for an output file - create
a name for the file which will be handed off to LMOS. The file name should
have a "TXT" extension. This step produces an undelimited ASCII file with
the following format:
BBxxxxxxxxxxxxxxxxxxBOOOAOOl ( pad out to BO characters )
B = Blanks
x=alphanumeric (18 characters)
