I am very sorry to hear that Gerry suffered from heart attack.
Although I am relieved to know that his condition is now upgraded, I
really wish his quick and complete get over.
Gerry has done enormous work for developing OPE-L discussion.
OPE-L, without Gerry, is unthinkable.
He has always answered to my questions very kindly, and I am alway
thankful for that.
With my best regards to Gerry.
