While Facform is running

After invoking Facform with Keyword file, PHYS.KSP


Facform reports its operation to the screen


FACFORM Version No. 1.20, October 1, 1992

Copyright (c) 1990-1992, John M. Linacre

Please mention the version number when contacting us with a question about Facform.


Phase 1: Examining the DOS command line..

Any file names or keywords on the DOS command line are processed.


Phase 2: Processing keywords from "PHYS.KSP"..

Keywords in the keyword file are scanned and validated.


Opening the $Spoutput file: "PHYS.FSP"..

The output file for Facets specifications is opened.


Phase 3: Reading $Spinput file "PHYS.SPC"..

The previous file of Facets specifications, if any, is processed:


Number of facet - number of elements found:

1-1 1-2 1-3 1-4 1-5 1-6 1-7 1-8 1-9 1-10 1-11 1-12 1-13 1-14 1-15 1-16 1-17

1-18 2-1 2-2 2-3 2-4 2-5 2-6 2-7 2-8 2-9 2-10 2-11 2-12 2-13 2-14 2-15 2-16

2-17 2-18 3-1 3-2 3-3 3-4 3-5 3-6 3-7 3-8 3-9 3-10 3-11 3-12 3-13 3-14 3-15

3-16 3-17 3-18 3-19 3-20 3-21 3-22 3-23 4-1 4-2 5-1 5-2 5-3 5-4 5-5 5-6 5-7 5-8

5-9 5-10 5-11 5-12 5-13 5-14 5-15 5-16 5-17 5-18 5-19 5-20 5-21 5-22 5-23 5-24

5-25 5-26 5-27 5-28 5-29 5-30 5-31 5-32 5-33 5-34 5-35 5-36

As Labels= specifications are processed from a $Spinput file, or new elements are discovered in a $Input file, they are added to the array of element numbers and labels. 1-1 means "in facet 1, there is 1 element so far," "5-36" means that "in facet 5, there are 36 elements so far."


Opening the $Input file: "PHYSDAT.txt"..

The input data file is opened, ready for processing.

Phase 4: Reading labels from Input file "PHYSDAT.txt"..

The input data file is processed once, looking for new element numbers and labels to add to the element array. In this case, there are none to add.

If you know that all element labels are in the $Spinput file, specify $Given in the Facform keyword file, or on the DOS command line.


Phase 5: Writing to $Spoutput file "PHYS.FSP"..

Facets specifications are written to the $Spoutput file


Phase 6: Writing formatted $Output file "PHYS.DSP"..


The data is written to the $Output file in Facets format. The bar-chart shows the progress through this operation.


Input file lines: 4

Input file line groups: 4

Label specifications written to $Spoutput file: PHYS.FSP

Formatted ratings written to $Output file: PHYS.DSP

Number of ratings = 144  Lines of data = 8

At the conclusion of the run, summary information is displayed on the screen.

Check that the number of ratings matches what you expect from the $Input file.

According to Wikipedia, the human body requires about 30 minerals, maybe more. There are 60 naturally-occurring minerals in the liquid Mineral Supplement which I take daily.
