I have a customer who recently upgraded from Desigo V6.0 to V7 QU2. They have several lengthy PPCL programs that trigger a read error when attempting to open them in Desigo. Interestingly, the same programs can be viewed successfully via Telnet or Launchpad.

I'm aware there's a PPCL patch available for sites upgrading to V6 QU1/QU2. Is there a similar patch or workaround available for V7 QU2?

Alternatively, could a syntax error within the PPCL program be preventing it from displaying correctly in Desigo?

There is new QU3 update, maybe it could help in your case.

Please read notes about it.

I was not aware a V6 patch existed for that issue. I do shorten my program lines when I see this happening. That is a permanent and robust solution IMO.
