Rex,

You can create a function that that does what you want and also returns the value of memo field and reference it in the field expression instead of memo field. Something like

* Report Field expression 
myfunction(mymemofield)
...
FUNCTION myfunction(tcMymemofield)
* Do whatever you want here
...
* return memo filed value
RETURN tcMymemofield

This will be used when the memo is printed to call the function to add the index value to a database that will be used at the end of the report to print a second report. The call needs to be in the report to know the page number value (_page). Obviously, the 'trigger value' must not print on the report.
