Yup, mispelled it and realized th error :)

RS, and its Perl equivelent, which I forget, mean that you can read in
full multiline records.
(I am coming into Python via Perl from AWK, and trying to get a grip
on the language and its idions)
Thanks to All
Oh, Awk is far more than a text processing language, may be old (like me!)
but useful (ditto)

Was that the Color Computer III running OS9 Level II for an operating system, that you're talking about? Motorola 6809 processor? HELLUVA little computer! OS9 was a bit quirky, though, even for a UNIX clone. -- http://mail.python.org/mailman/listinfo/python-list

I also found that the whole system ran faster and better (especially under OS9) with two floppy drives. Programmed that puppy in OS9BASIC and 6809 Assembler...Much preferred the Assembler. A lot less confusing than Microsoft's assembler! But I had to shift over to PCs when I figured out that Tandy wasn't supporting the CoCo system. They took the 40-connector extension boards out of their inventory and that killed the market right there. Another raid from Microsoft? -- http://mail.python.org/mailman/listinfo/python-list
