# form.awk is an awk script that requires access to 2 files: The #first file is called "form.letter". This file contains the format #for a form letter. The awk script uses another file, "data.form", #as its input file. This file contains the information that will be #substituted into the form letters in the place of the numbers 
#preceded by pound signs. Today's date is substituted in the place #of "@date" in "form.letter".

BEGIN{ FS=":"; n=1
while(getline < "form.letter" >  0)
    form[n++] = $0   #Store lines from form.letter in an array
"date" | getline d; split(d, today, " ")
    # Output of date is Sun Mar 2 14:35:50   PST 1999
thisday=today[2]". "today[3]", "today[6]

	    gsub("@date", thisday, temp)
	    gsub("#" j, $j , temp )
