13		-
14		-* Variable name : that will be referred to inside the [[Loop connector>>doc:iXPath V3.Connectors.Scenario.Loop.WebHome]]
15		-* Append : a checkbox, If checked, the files will be added to the end of the stack. Otherwise, they will be prepended.
16		-* Stack in variable : Select this option to stack the files into a variable. Otherwise, the files will not be added.
17		-* Return variable : When selected, the files stacked into the variable will serve as the output file for the connector. If not, the input file will be used as the output.

21		-The 'Stack' must be combined with a 'Loop' connector to make it useful, depending on each use case.

28		-we set a variable named 'var', and put the loaded files from 'LoadFile2' as value.

33		-then, we retrieve this variable using the 'Loop' connector, and iterate over the set, and make a limit of iterations as 20.
