Using the %ftpdifffiles and %ftpdiffnum Variables

These variables are set by the FTPDIFF and FTPGETDIFF script commands respectively.

The %ftpdifffiles variable contains the total number of different files that the FTPDIFF command detects when scanning the FTP site file system within the directory and subdirectories (if any) specified.

The %ftpdiffnum variable contains the sequential number of a given file returned by the FTPGETDIFF command.

Used together, it is possible to use these variables to know how many more differences there may be when performing a script loop calling FTPGETDIFF to identify multiple differences.

More specifically, %diffnum = %difffiles after FTPGETDIFF has been issued a sufficient number of times to find all the currently identified differences detected by the most recent FTPDIFF command.
