Arguments

 

resultant-string

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

   String that LIB$GET_INPUT gets from the input device. The
   resultant-string argument is the address of a descriptor pointing
   to the character string into which LIB$GET_INPUT writes the text
   received from the current input device.
 

prompt-string

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

   Prompt message that is displayed on the controlling terminal. The
   prompt-string argument is the address of a descriptor containing
   the prompt. Any string can be a valid prompt. By convention
   however, a prompt consists of text followed by a colon (:),  a
   space, and no carriage-return/line-feed combination. The maximum
   size of the prompt message is 255 characters. If the controlling
   input device is not a terminal, this argument is ignored.
 

resultant-length

   OpenVMS usage:word_unsigned
   type:         word (unsigned)
   access:       write only
   mechanism:    by reference

   Number of bytes written into resultant-string by LIB$GET_
   INPUT, not counting padding in the case of a fixed string. The
   resultant-length argument is the address of an unsigned word
   containing this number. If the input string is truncated to the
   size specified in the resultant-string descriptor, resultant-
   length is set to this size. Therefore, resultant-length can
   always be used by the calling program to access a valid substring
   of resultant-string.
