RE: Pointer Question

["Smith, Nelson" <NSmith@xxxxxxxxxxx>]

So what is the best way to clear previously used occurrances?  Do I have to
loop through all of them clearing them one at at time?

Further debugging did prove that after using 8 occurs, then resetting the
MODS to use 1 byte, then starting over and reallocating one occurrance's
worth of memory at a time, on the fifth occurrance, I began picking up
previously loaded data. So, apparently, REALLOC does not clear the new
memory it is allocating.  At least not if it has been used previously in the
same job?
