Using the %difffiles and %diffnum Variables

These variables are set by the DIFF and GETDIFF script commands respectively.

The %difffiles variable contains the total number of different files that the DIFF command detects when scanning the local PC file system within the folder and subfolders (if any) specified.

The %diffnum variable contains the sequential number of a given file returned by the GETDIFF 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 GETDIFF to identify multiple differences.

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