TIB: [Sorry!!] Re: Strings Answer to basic question

Even on the 86?!? Ooops! And I'm always to telling everyone to RTFM. Shame on me!!!!!
 
Sorry for the bad info, and thanks for the correction Jeff.

But, you don't have to delete ANY y= variables. If LinR is executed without the third argument, it's just stored in RegEq, which will be cleared anyway whether or not the equation is stored to a y= variable. So just use RegEq instead of a y= variable.

Or on the 86, replace y1 with y99, wich is almost never used. Then delete it with DelVar()

This works fine, but to avoid deleting y1 (or when using a TI-85), remove the ",y1" from the end of the LinR statement and in the next Eq>St statement, replace "y1" with "RegEq".

I'm surprised that nobody has posted the following yet. It was on the list a while ago.
 
This is for the '86, I don't know about he 83's commands, but I think it should work on there too.
 
"ABC" -> S                 *Create a String
58 -> N                    *The number I want to concatenate with the string
 
LinR {1,2} , {N,N} , y1    *Linear Regression with points (1,N) and (2,N).
                           *The  resulting equation is stored in y1.
Eq>St(y1,S2)               *Store y1 to S2 as a string. The value of S2 is "58+0x"
sub(S2,1,lngth S2-3) -> S2 *Chop of the "+0x" part
S+S2 -> S                  *concatenate the strings
 
No I wonder though, can you store the equation resulting of a linear regression to an equation variable on the TI-83? I believe that on the '82 the equation was automatically stored to a variable called "RegEq", or something of the sort... Would someone with an 83  please check the manual?
