  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

ISO 3901:2001. ISRC example (formatted): FR-Z03-98-00212 .

according to the ISRC specs there is no checksum, so the verification part is an approximation.

pMode = "format": formats given string to readable ISRC or throws an error text if input is not correct.
pMode = "check": tests on correct input only. returns 1 if input is incorrect, 0 if correct (!)
