That is precisely what I want.  I have a column with entries that are
either all digits, or mixed digits and letters. Without that leading
single-quote, the numbers are right-aligned, the others left-aligned.

I also use chr("39") in to left-justify any MDY/ entries: easier on the
eyes if the next column contains text.

To sum column "f",from the top to row N, the spreadsheet formula is

	SUM(f1:fN)

Only numbers in the column get added (text is ignored), so it's OK to
start at row 1.  In filePro, @RS is the total number of records; since
my first two rows have titles for the columns, the (@RS)th record will
be on row @rs+2.  For columns E through K, the processing is:

	::rw=@rs+"2":			
	::rpt(5)="=sum(e1^Ae"{rw{")":
	::rpt(6)="=sum(f1^Af"{rw{")":
	 ,...
	::rpt(10)="=sum(j1^Aj"{rw{")":
	::rpt(11)="=sum(k1^Ak"{rw{")":

(where '^A' is the CTL-A that filePro uses for a colon in the ASCII
version of the processing table).
