DEFSTR                   Define Variable(s) as String

 DEFSTR letter[-letter] [,letter [-letter]]...

    Declares one or more variables to be of type string.

   ----------------------------------------------------------------------

      Notes:    All variable names beginning with any of the specified
                letters (case-insensitive) will be strings, unless a type-
                identifier character (%, #, or !) is used to override the
                DEFSTR declaration.

                The DEFSTR declaration must be read by the compiler before
                any statements in which the declared variables are
                assigned or used. The compiler reads from beginning to
                end, without regard for execution path.

                You cannot avoid a DEFSTR declaration by direction the
                execution path around it.

                DEFSTR statements do not affect symbolic constants.
