Difference between revisions of "Redirecting pointers"

Revision as of 18:59, 13 November 2005

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

I believe the array of pointers to be transferred is stored in:

  ^UTILITY("DIT",$J,0)=0
  ^UTILITY("DIT",$J,0,index)=FileNumber^Pointer^FieldInfoCodes
  ^UTILITY("DIT",$J,DeletedIEN)=NewIEN;GlobalRef

Example of deleting two entries from file #50
^UTILITY("DIT",5946,0)=0
^UTILITY("DIT",5946,0,1)="50^62.05^*P50'" <--- File 50, field 62.05
^UTILITY("DIT",5946,0,2)="50^905^P50'X"

The transfer seems to be called with this:
  do ASK^DITP
  if %=1 do PTS^DITP
