Re: page n of x

[Jim Langston <jlangston@xxxxxxxxxxxxxxxx>]

Well, think about it... how is your program going to know how many pages there
are in total?  Say, perhaps, you are reading through a file a line at a time, 
when you print
out the first record, how is your program to know how many records there are?  
And then
there is the matter of how many lines you are printing on each page, how many 
are taken up
by the header and footer, etc...

If you do need to know the total number of pages you are going to have to 
determine this
before hand.  In the case given it should be a simple matter of determining how 
many records
in the file (not counting deleted records) from an API, and dividing that by 
the number of records
you are printing on each page.  I have done this kind of thing before.

You will have to calculate this in your program before you print the first 
record, however (you could
print it at the bottom of the page, but same difference).

As long as you know at line 1 how many detail lines you will be printing, you 
can calculate the total
number of pages.  If you don't know the total number of pages before you start, 
there is no way to
calculate it.  It would be possible to cycle through all your 
input/records/whatever first without printing
out anything, then when you determine how many pages it will be cycle through 
them again and actually
print them out (this is what Microsoft Word does to determine total number of 
pages.  See the repagenate
function).
