Redirecting pointers

I am going to use this page to hold notes about redirecting pointers. I want to be able to programatically change all pointers in all records that point to a given record, to point to a different pointer.

This is done in Fileman when a record is deleted and there are pointers to that record. The user is given the option to delete all pointers, or to redirect them to another record.

Notes:

The code that asks: "DO YOU WANT THOSE POINTERS UPDATED (WHICH COULD TAKE AWHILE)?" is in DITP.m
