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.

	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 <Control file name> [options].

 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 starting byte position of the
 field, length of the field.

 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
2,4
10,1

The input file name is C:\DATA\STC.TXT.

The output file name is C:\DATA\LESS100.TXT.

The 2,4 tells the utility to take start the field a byte 2 and the 
field length is 4.

The 10,1 tells the utility that the next field starts a byte 10 and its
length is 1.


 
 OPTIONS
 -------
1) -d         This will tell the utility to make the output file
              delimited.

2) -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.

3) -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.   (Try It !)



Registration

  I will keep improving the program if I know enough people are

  If you register for the full fee, and enclose a Shipping and
  Handling fee of $3 I will send you the latest versions of JSFIELD and
  Some Free Demo's.  if you decide to use it after a trial period. I will 
  also send other File related shareware programs.
