Hi Karl, hi all
@maintainers:
According to the below I tried to improve the Org manual with the
attached patch, please review and apply.

Yes, with all the explanations of how the formulas work your github
novoid/org-mode-workshop contains a very nice spreadsheet
documentation, for more than just referencing remote tables. Can you
please link the section here with mentioning that it contains
explanations of how the formulas work?:
http://orgmode.org/worg/org-tutorials/index.html
Your new example in github novoid/org-mode-workshop with
@2=remote(Income2012h, @3$$#)
- motivated by my example in the current Org manual
- that interprets text as a Calc algebraic expression, which is
subject to reformatting
reminded me of that just copying fields is better done with a Lisp
formula "'(identity [...])", see attached patch for the Org manual.

-For Calc formulas and Lisp formulas @code{@@#} and @code{$#} can be used to

+One of the very first actions during evaluation of Calc formulas and Lisp
+formulas is to substitute @code{@@#} and @code{$#} in the formula with the
+row or column number of the field where the current result will go to. The
+traditional Lisp formula equivalents are @code{org-table-current-dline} and
+@code{org-table-current-column}. Examples:
-@example
-if(@@# % 2, $#, string("")) @r{column number on odd lines only}
-$3 = remote(FOO, @@@@#$2) @r{copy column 2 from table FOO into}
- @r{column 3 of the current table}
-@end example
+@table @code
+@item if(@@# % 2, $#, string(""))
+Insert column number on odd rows, set field to empty on even rows.
+@item $2 = '(identity remote(FOO, @@@@#$1))
+Copy text or values of each row of column 1 of the table named @code{FOO}
+into column 2 of the current table.
+@item @@3 = 2 * remote(FOO, @@1$$#)
+Insert the doubled value of each column of row 1 of the table named
+@code{FOO} into row 3 of the current table.

-O(N^2) because table FOO is parsed for each field to be copied.} for large
