Library /sys$common/syshlp/dbg$help.hlb DEBUG, Messages, STRNGPAD  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 string operand lengths don't match, shorter padded with blanks on
 the right

    Facility: DEBUG, VMS Debugger

    Explanation: The operands of a string comparison ( 'ABC' < 'AB' )
    did not have the same length. The shorter one is blank extended
    on the right.

    User Action: Use strings of the same length.
