How can I control the error output in CIB merge?

Tip: Loops in the raw text: NEXT DEF instead of Multi-CSV

CIB merge apparently has problems with large data quantities. It uses up more and more memory and causes the system to "seize up".

How can I use quotation marks in CSV field contents when the field contents are enclosed in quotation marks?

I have problems with semicolons or line feeds in CSV field contents which are causing the merge run to terminate. What can I do?

If I insert {IF (PAGE} <>{NUMPAGES} "Page {PAGE} of {NUMPAGES}" ""} into an RTF file, it works fine with Word, but with CIB merge the condition is not evaluated correctly and always returns False.
