Facform creates Facets specification and data files from a Keyword file and raw data |
i) The Facform keyword file, "keyfile".
This contains a list of "keyword=value" statements that Facform uses to convert the input raw data into data formatted for Facets. You are prompted for this when Facform starts.
ii) The unformatted, raw, input data file ($Input=).
This file contains the data to be converted to Facets format. It is usually a flat file, but many logically organized file structures can be processed by Facform.
iii) Optionally, a previous Facets specification file, if any ($Spinput=).
As Facform processes the input data, it builds a table of element numbers and names. Facform can use a pre-existing Facets specification file as the basis of this table, adding new element numbers and names to it, as necessary. This means that newly identified elements are not accidentally assigned the same numbers as previous elements. Also previous element anchor values and other Facets specifications are transferred into the newly constructed Facets specification file.
iv) The DOS command line.
C:> FACFORM keyfile outputfile keyword=value keyword=value ..
This contains the name, "keyfile", of the keyword file.
It can also contain the name, "outputfile", of the output formatted data file.
It can also contain "keyword=value" statements, which take precedence over those stored on disk.
