Re: HP 49G+ ROM version Message #1 Posted by Ernie Malaga on 24 Nov 2003, 3:29 a.m. Hi all. I've been trying to find information about the "|" operator (vertical bar), but the manuals don't even mention it. Can any of you enlighten me? Thanks. -Ernie

Re: HP 49G+ ROM version Message #2 Posted by JasonG on 24 Nov 2003, 3:42 a.m., in response to message #1 by Ernie Malaga Hi there, IIRC, the | operator is called 'where', so that you can define the value of a variable in an expression.
