/*+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
.LANGUAGE    C
.IDENTIFICATION  main module MIDASGO
.AUTHOR  K. Banse 	ESO - Garching
.KEYWORDS MIDAS environment, keywords, logfile
.ENVIRONMENT   VMS and UNIX
.PURPOSE
  initialize the system keywords from file SYSKEYS.DAT (ASCII file)
  and write keywords to binary file MONITOR.KEY,
  where MONITOR is the image display station used by MIDAS
  use OSY_TRNLOG to determine actual image system, user + graphics terminal
  and initialize
.ALGORITHM
  the keywords are read from file SYSKEYS.DAT as follows:
  record 1: name / type / length / R
  name = keyword name
  type = I or R or C or D
  length = length of keyword values in longwords (type I or R)
  or bytes (type C) or quadwords (type D)
  R  only, if it is a MIDAS reserved keyword
  the reserved keywords must be the first ones in the file!
  record 2: keyword values in a format according to type

.VERSION  [1.70] 880513: initialize pointers in source code only ...
