There are no troublesome characters. If it's CHARZ

There's no such attribute.  Do you mean VARYINGZ?

then a '00'X marks the end of the string, as in C. Otherwise there is an 
explicit length
that is the same regardless of what characters are in the string. The length may
be determined at, e.g. compile time, block entry, or may be dynamic (VARYING).

And it can be explicitly determined at run time.
