Library /sys$common/syshlp/basichelp.hlb Compile time errors, LENDYNSTR  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  ERROR - The program contains a  dynamic  string  variable  declaration
  that  specifies  a  string  length.  Length specifications are allowed
  only for fixed-length strings; remove the  length  specification  from
  the dynamic string or allocate the string in a MAP or COMMON.
