The GLINE routine is deprecated.

xcall GLINE([length, ]buffer[, prompt])

Arguments

length

(optional) The variable that will be loaded with the length of the input line. (n)

buffer

The variable that will be loaded with the input line stored left-justified over blanks. If the buffer area is too short, only the leftmost portion of the input line is stored; the remainder is discarded. (a)

prompt

(optional) The message displayed as a prompt for input. (a)

Discussion

The GLINE subroutine gets a line of input from the terminal device and performs a READS statement.

The length argument contains the same value that %RDLEN (or %RSIZE) returns when a READS statement is used.

If the prompt argument is specified, you must also specify the length argument.

On OpenVMS, GLINE uses the OpenVMS LIB$GET_INPUT routine to get an input line from the device assigned to the logical name SYS$INPUT.

Examples

.define TTCHN           ,1
record
    msg                 ,a50
    lng                 ,d2
     alng                ,a2 @lng

proc
    open(TTCHN, o, "tt:")
    writes(TTCHN, "Tracing input until *end*")
    while (msg .ne. "*end*") do
      begin
        xcall gline(lng, msg)
        writes(TTCHN, "lng = " + alng + ", Msg: "+ msg)
      end
    stop
end
