Given a FORMAT text that produces output in aligned columns makes it easy enough to meet the other requirements. To cause texts to be aligned left, append sufficient spaces to each output text, and for centred text, half that number. This relies on the special intrinsic function REPEAT(text,n) returning a varying number of characters - CHARACTER functions have to return a ''fixed'' number of characters, until the standardisation of varying-length strings in F2003 ''et seq''. Earlier Fortrans lack the REPEAT function, but its effect can be gained via something like CHARACTER*66 SPACE, where SPACE is set to spaces, and SPACE(1:N) is used where REPEAT(" ",N) is desired. And if messing with variable FORMAT is unwanted, the REPEAT scheme can be used for the right-justified output also.

SUBROUTINE RAKE(IN,M,X,WAY) !Casts forth text in fixed-width columns.

Collates column widths so that each column is wide enough for its widest member.

CALL RAKE(IN,M,"$",+1) !Align right.

END !That's all.

Every line of output starts with a space, and if it were to be sent to a lineprinter, this would be used as the carriage control character (meaning, advance one line then print the rest) - the first column does not need to be set off by one space from the previous column, but rather than devise special treatment it is spaced off anyway. The free-format output statements also start with a space. Output:

A file opened with a Format option describing the column format(s) can be addressed like a standard in-memory array. In addition the DLG function ([http://www.HicEst.com/MatrixExplorer.htm MatrixExplorer]) allows this text/numeric file to be edited or visualized in many ways, but string columns are always left adjusted while numeric columns are right adjusted. Export is possible.

"Further,$allow$for$each$word$in$a$column$to$be$either$left$\n"

The following procedure solves the problem. It takes the string to be operated on as input, and an optional alignment parameter, which defaults to centred alignment. The aligned text is returned, as a string, which can then be printed.

AlignColumns := proc( txt, align :: { "left", "right", "centre" } := "centre" )

uses StringTools;

Join( J, "\n" )

end proc:

For the sample text, we get the following results.

Further, allow for each word in a column to be either left

justified, right justified, or center justified within its column.
