Graphic (n) Varyingz

Graphic (n) is a graphic-string variable. The VARYINGZ (VARZ) attribute causes the string variable or function to hold or return values of varying lengths. Internally, the varyingz graphic strings are a stored as a sequence of characters terminated by a ‘0000’x byte, and are not padded to assume their maximum length, n. The representation of a varying string variable in storage is such that any string up to n double-byte characters may be held by the variable.
