 * FUNCTION:    myGoToPedit
 *
 * DESCRIPTION: This routine is an example how to go to a pedit memo from another application
 *
 * PARAMETERS:	theRecIndex - index of the memo [first memo's index is 0]
 *					N.B. Use theRecIndex = noRecordSelected [= 0xFFFF] to go to ListView
 *				theCursorPosition - self-evident
 *				theSelectionSize - self-evident
 *					N.B. make sure that theCursorPosition + theSelectionSize <= StrLen (your memo)
 *				theWhichMemoDB - if 32 then it opens a 32K pedit memo, otherwise a 4K pedit memo
 *				theWhichPedit -  if 32 then it opens pedit32, otherwise pedit or peditLight
 *					N.B. By default, it opens peditPro if it is installed.
 *
 *
 * RETURNED:	 nothing
 *
