Will delete any probe whose name ends with (#) - so PRB(1) for example. The only exception is that it will not delete the currently active probe. If you only want the probes to be temporary / relate to a specific WDB then I would suggest storing them in the LDB. Once you have qualified your probes you can use CPYOBJ to copy them into the LDB and then DELEDBPRB to remove them from the EDB. Once they are in the LDB, whenever you open your WDB you can use an EDBUD command at the start of your program to copy them back up to the EDB and a DELEDBPRB command at the end to delete them again.
