This would be a version issue. Seq was cleaned up with the CTP release.
One thing I hadn't noticed before is, in the foreword of Foundations of F#, it says "Robert's book describes F# 2.0, the latest release of the language at the time of writing".
So you'll just have to download F# 2.0, and all examples should be fine ; )
You're better off using the "for x in collection" syntax when working with untyped listed, which is why they have been clean up. I think I say that in the book. Don wrote the forward so ask him were to download version 2.0 ;)
Cheers,
Rob
Thank you all for the responses.I have taken note of the advisories. Thanks. I was chiefly concerned at this point whether I had messed up the 1.9.6 install.fwiw, I first ran across this issue while working a sample from the Expert F# book (Mandelbrot), which was purportedly built with 1.9.2. In that build, these functions are defined in ienumerable.fs, which appears to have been revised/removed from 1.9.6. I only mention it in case another newbie runs into it.
I appreciate the help very much. Thanks again.

Hello.
I am new to F# and am trying to get a handle on it by working through examples in the books and articles. I am running into a situation where the untyped functions (e.g. Seq.untyped_map, Seq.untyped_iter, etc.) are not defined when I run the published samples.Am not sure if this is a version issue and/or plain ignorance on my part. I'm using 1.9.6.2.Any insights would be appreciated.Thanks.
