If you have a minute, would you try this alternative?
get: func [myVar /local walkDB] [
walkDB: myDB
while [not tail? walkDB] [
rec: first walkDB
either rec/fType = myVar [
remove walkDB
][
walkDB: next walkDB
]
]
]
I don't have time to test it right now, but I suspect that your
problem comes from mutating the same series that FORALL is trying
to walk through. The only thing I'm doing different in the
snippet above is explicitly managing the remove-or-step process.
