- Introduction
-
-
- programmers are frequently asked to extract and format
- data for the PC. It is not enough for the programmer simply to
- pull off the records of interest to the user. Usually, the records must be
- formatted to create a set of fields appropriate for "importing"
- into the PC worksheet. In a typical company, hundreds of man-hours
- are spent each year in creating the small ad-hoc programs required
- to generate such data.
-
- The JSFIELD utility greatly simplifies the task of manipulating
- data for use in a PC environment. JSFIELD provides the following
- features:
-
- 1. Selective extraction of fields from an input record
-
- 2. Data output in either delimited ASCII or non-delimited ASCII
- format.
-
- 3. Selectable column position ordering of extracted fields.
-
- 4. Ability to write the same input data into multiple output
- fields.
-
- 5. Record selection capability based on record field contents.
-
- 6. Optional output record count limit parameter.
-
- 7. Formatting of string field with quote marks and numeric
- fields with explicit zeros.
-
- 8. Suppression of unwanted characters within selected fields.
-
- 9. Creation of constant string output fields.
-
- 10. Conversion data from EBCDIC to ASCII format.
-
-
-
-
- The JSFIELD program must be provided with control information
- to govern its execution. This information is read from a control file.
- The control file is a standard PC text file that can be created
- with any ASCII text editor.
-
- To run JSFIELD type at the prompt: JSFIELD [options] <Control file name> .
-
- THE CONTROL FILE
- ----------------
-
- The first line of the control file identifies the input file name.
-
- The second line of the control file identifies the output file name.
-
- Subsequent lines of the file provide field extraction control information.
- Each field exaction control line contains the type of field ,starting byte
- position of the field, length of the field and a mask if needed.
-
- The following sample control file illustrates how control
- information is provided to the JSFIELD program.
-
- Contents of a sample JSFIELD control file, JSFIELD.CTL:
-
- C:\DATA\STC.TXT
- C:\DATA\only100.TXT
- c,2,4,<>,John
- n,10,1,=,1
- C,5,3
- N,24,7,<,10000
-
-
-
- The input file name is C:\DATA\STC.TXT.
-
- The output file name is C:\DATA\LESS100.TXT.
-
- The first field extract control record (c,2,4,<>,John) indicates that
- the data to be extract is a string field(characters to be surrounded by
- quotes) will be extracted from byte position 2 and The logical length
- of the field is 4 characters. The selection data indicate that the input
- record will be discarded if the field value is equal to John.
-
- The second field extract control record (n,10,1,=,1) indicates that the
- data to be extract is a numeric field and it will be extracted from
- byte position 10 and the logical length of the field is 1 character.
- The selection data indicate that the input record will be discarded
- if the field value is not equal to 1.
-
- The field extract control record (C,5,3) indicates that the data to be
- extract is a string. The leading and trailing spaces will be removed because
- you used a Upper case 'C' character. The field will be extracted from
- byte position 5 and the logical length of the field is 3 characters
- long.
-
- The field extract control record (N,24,7,<,10000) indicates that the data to
- be extract is a numeric field and it will removed leading zeros because
- you used a upper case 'N' character. The field will be extracted from
- byte position 25 and the logical length of the field is 7 characters long.
- If the field is not less then 10,000 the input record will be discarded.
-
-
- JSFIELD Output field type codes
- -------------------------------
-
- The following are valid codes for designating output field types:
-
- STRING FIELDS
- -------------
- 1) c (Lower case) String field. (Surrounded by quotes).
-
- 2) C (Upper case) String field. (Surrounded by quotes, Leading and
- trailing spaces will be removed).
-
- 3) u (Lower case) String field. This will convert the string to
- all uppercase. (Surrounded by quotes).
-
- 4) U (Upper case) String field. This will convert the string to
- all uppercase. (Surrounded by quotes, Leading and
- trailing spaces will be removed).
-
- 5) l (Lower case) String field. This will convert the string to
- all lowercase. (Surrounded by quotes).
-
- 6) L (Upper case) String field. This will convert the string to
- all lowercase. (Surrounded by quotes, Leading and
- trailing spaces will be removed).
-
- NUMERIC FIELDS
- --------------
- 1) n (Lower case) Numeric field (Leading and trailing spaces will
- be removed).
-
- 2) N (Upper case) Numeric field (Leading and trailing spaces will
- be removed. also Leading zeros will be removed).
-
-
- JSFIELD Output file mask code
- _____________________________
-
- The following are valid codes for designating output field mask:
-
- 1) <> Take all record not equal to the value of the
- data field.
-
- 2) < Take all record less then the value of the data
- field.
-
- 3) > Take all record greater then the value of the
- data field.
-
- 4) = Take all record equal to the value of the data field.
-
-
-
-
- OPTIONS
- -------
- 1) -bz This option will tell the utility that the input file is not
- CRLF and the record length is z long, also make the output file
- without CRLF.
-
- 2) -Bz This option will tell the utility that the input file is not
- CRLF and the record length is z long, also this will add CRLF
- to the output file.
-
- 3) -ez This option will tell the utility that the input file is EBCDIC
- and the record length is z long, also make the output file ASCII
- without CRLF.
-
- 4) -Ez This option will tell the utility that the input file is EBCDIC
- and the record length is z long, also the output file will
- be ASCII with CRLF..
-
- 5) -A This option will tell the utility that the input file is CRLF
- but don't make the output CRLF.
-
- 6) -d This will tell the utility to make the output file delimited.
-
- 7) -a In some system a delimiter after the last field on the record
- will be needed. This option will insert a delimiter after the
- last field on each record.
-
- 8) -nz This option will tell the utility to only extract z number of
- record(s).
-
- 9) -s This option will put the utility into fast and stealth mode.
- fast and stealth mode will surpress the graph that shows on
- the screen when JSFIELD is executed and the counters will
- only be displayed at program termination. The advantage
- of using this option is that the utility will run
- MUCH, MUCH FASTER.
