- FIELD: Tara Datafile Utilities, v. 2.0, (c) 1987 by David C. Oshel
-
- Projects selected fields from MailMerge-type records to standard output.
-
- Usage: C>FIELD 1 2 7 <names.dat >small.dat
- C>tsort 8 <names.dat | FIELD -s. 3:20 12 8 | more
- C>pick -f* 8 eq X <names.dat | FIELD -f* 2: 1 2 3 >temp
-
- Your INPUT DATAFILE (with <) is chosen on the command line. You may give a
- complete pathname to another drive and/or subdirectory.
-
- The first example (with >) COPIES fields 1, 2 and 7 to records in "small.dat".
- The second FORMATS field 3 in 20 DOTS, fields 12 & 8 are formatted implicitly.
- The third sets field separator to "*", and FORMATS all fields in default width.
-
- Formatted output, selected by the "fieldnumber:width" style, is most usefully
- received on-screen. If the contents of a field are longer than the width, the
- field is truncated. Fields are left justified, but if the data is apparently
- numeric, it will be right justified. Output remains in standard record format
- if there's NO COLON argument. Default width is SAME AS LAST or else 15 spaces.
- An extra space appears between formatted fields. A field number may not be 0.
