Good suggestion except that the gyzma # is not accessible in Smath. Not directly accessible via the Shift 3 keyboard, neither via the extended Alt 035. Smath 5346, XP Home SP3.

# is serial text format for empty placeholder. You do not need to type it, just leave it empty. Currently this throws an error but that could perhaps be changed.
