•If you are opening multiple files be sure to save the File Numbers into BPV Integer Variables for use in other areas of the module.

•

•If you save a File-Number in a temp Local variable, then it will be lost once you leave the script section.

•

•Normally one would open the files in the Before Test script and close in the After test script. The BPV Integer File Number variables can then be used to read and write from the various files at the same time. When using the OpenAppend function the file can be closed and opened multiple times during the test, since the writing will always be appended to the end of the file.
