I miss them. There's so much one could do right now with precious expressions like
find, remove, replace, left, right, gettoken, mid...
I only noticed that there was the expression len to get the string length so far.
Several engines I did in Classic could already work in C2, if only it wasn't missing some of those expressions. I suspect it wouldn't be too laborious to add, so let me carefully ask: will we see more text expressions soon?
