To start Facform under DOS

At the DOS prompt,


Either enter:



and the program will ask you for the name of your keyword file with

Keyword file name:


Type in the name of the keyword file you want, e.g.



Or enter:

C:> FACFORM keyfile

where keyfile is the name of your keyword file, e.g., KCTkey.txt


Or, for advanced users, enter:

C:> FACFORM keyfile outputfile keyword=value keyword=value ..


keyfile is the name of your keyword file,

outputfile (optional) is the name of the file to hold your formatted data,

keyword=value are keywords like those in the keyword file.


The keywords entered here take precedence over those in the keyword file.


For entries on the DOS command line blanks are used as separators. Blanks are not allowed within keywords. This is correct:

C:> FACFORM facform\KCTkey.txt KCTDAT.txt $SPOUTPUT=KCTSP.txt


But, $SPOUTPUT=  KCTSP.txt is incorrect due to the blank between = and KCTSP.txt


keyword=details represents keyword lines like those included in a keyword file. The keywords given here take priority over those in the keyword file.


To include blanks in values, place them inside quotes.


The following is valid:

C:> FACFORM facform\KCTkey.txt $PRINT="This is displayed"

But, not valid due to the extra blanks, is:

C:> FACFORM facform\KCTkey.txt $PRINT=This is displayed
