Hi Frank,

I use a right-hand-side-only delimiter for this purpose.

(math (concat (around* "<nobracket>" "q" "|") (rsub "C") "=y"))

Dear all,

I wonder how to input the symbol for restriction of function? Now I input, say,

(math (concat "q|" (rsub "C") "=y"))

which will generate, in my opinion, an incorrect spacing (see the space before and after "="). I also suspect that this is semantically incorrect.

Best wishes,
Frank
