PONS prints all user-defined names and their values. PONS is equivalent to PRINTOUT NAMES.

An optional input may be supplied which acts as a filter. PONS then only prints those names which start with the same characters as the second input. PONS S will, for example, only print those names which start with the letter S. This allows a more efficient use of this command when many names are defined.
