'Note: The DataTable "TDR_Wave" data storage area is NOT and should NOT be auto allocated
'in this program example!!! Therefore, "TDR_Wave" memory storage size should be allocated
'by the programmer. How to calculate memory storage size?
'Example: In this program when F2 goes high there are 8ea calls to "TDR_Wave", repeated
'let's say 30 times, will allocate memory for 240 waveforms. "DataTable (TDR_Wave,1,240)"
