Thanks Gysbert, that is actually my workaround but I would like a shorter and more elegant solutions. I could imagine that in qv some masking/wrapping methods like "\\" or " or """" & some statement & """" from other tools are possible.
I checked with a colleague whose been doing this awhile too. Don't think it has a standard escape syntax, although in some cases (Set Analysis , Field names in the load script) they are basically ways to have it ignore the single quote. But every usage scenario (variables , expressions etc...) is different and i just pick the best trick for the scenario.
