- SEPARATE vs. 1.0 by Jim Groeneveld, July 1987.
- ----------------------------------------------
-
- STATGRAPHICS can not read ASCII (fixed formatted) data files with multiple
- records (more than one record per case). In order to prepare existing data
- files of such a kind for STATGRAPHICS the program SEPARATE separates records
- with different record numbers or any number of records without record numbers
- within data files into separate data files for each set of occurring or
- corresponding record numbers. These resulting data files with one record per
- case may then be read independently into STATGRAPHICS one after the other.
-
- This utility may also be of value in preparing data files for other
- (statistical) programs. Records may actually be separated into different files
- based on any (numeric) field in the original file as long as the field is not
- more than 3 columns wide. Fields which contain characters or only blanks or
- are completely beyond EOL are treated as one discriminating mark and define one
- output file (with extension .-00) alltogether. All output file names are
- generated automatically. They consist of the original name and a numeric
- extension corresponding to the distinguishing field contents. If no
- discriminating field is specified the extensions consist of increasing values
- starting with .001. This implies that it is not allowed to input file names
- with this type of three digit numerical extensions. Existing output files with
- corresponding names and extensions will be overwritten without prompting!
-
- Optionally corresponding input records are compared with regard to their
- record lengths. If miscompares are found information about them are listed
- in a file with the original file name and the extension .MSG.
-
- Limitation: maximum input record length: 80 bytes (max. 80 characters per
- line) (the 'prehistoric' FORTRAN compiler does not allow to handle this
- number flexibly).
