> 1. String Compression

to find any unprintable characters use the following expression:

Strconv(laArray[2],15)

CHR(0), for instance, is unprintable.

> 2. Table Buffering

This is the case for newly added, unsaved records. The record exists in the buffer, which is why alias.field returns a value. It hasn't been loaded from the table, which is why OLDVAL() returns NULL. And it doesn't yet exists in the table on the server which is why CURVAL() returns NULL.
