What if the job required two file names? For example, one might want to read in the W365B47 image, but then divide it by the MB9401R image.

Within each directory, read all the files from that directory, process them, then write out the results to a different directory of the same name in a different location.

The modules can be linked together to form the batch operation. The flowchart modules pass messages to each other over their links, rather than passing images. Within the messages are two key elements, a directory name and a file name. The initial directory name is established as an absolute argument within the
