perform display-para thru display-para-exit.
close file1.
go back.
Para1.
read file1 into ws-file1
at end
end-of-file
set index-diff to index
not at end
move ws-file1-num to table-num(index)
set index up by 1
end-read.
para1-exit.
exit.

Display-para.
subtract 1 from index-diff.
perform until index-diff = 0
