6.8.11 Syntax Tables

Syntax tables do for input what compositions do for output: They allow you to teach custom notations to Calc’s formula parser. Calc keeps a separate syntax table for each language mode.

(Note that the Calc “syntax tables” discussed here are completely unrelated to the syntax tables described in the Emacs manual.)

The Z S (calc-edit-user-syntax) command edits the syntax table for the current language mode. If you want your syntax to work in any language, define it in the Normal language mode. Type C-c C-c to finish editing the syntax table, or C-x k to cancel the edit. The m m command saves all the syntax tables along with the other mode settings; see General Mode Commands.
