one-character-string

   OpenVMS usage:char_string
   type:         character string
   access:       write only
   mechanism:    by descriptor

   ASCII character string consisting of a single character followed
   by trailing spaces, if needed, that LIB$CHAR creates when it
   transforms the ASCII character code. The one-character-string
   argument is the address of a descriptor pointing to the character
   string that LIB$CHAR writes.
 

ascii-code

   OpenVMS usage:byte_unsigned
   type:         byte (unsigned)
   access:       read only
   mechanism:    by reference

   Single 8-bit ASCII character code that LIB$CHAR transforms to
   an ASCII string. The ascii-code argument is the address of an
   unsigned byte containing the ASCII character code.
