PRO REGIS

; Project     : SOHO - CDS
;
; Name        : REGIS
;
; Purpose     : Sets graphics device to REGIS mode.
;
; Explanation : SETPLOT is called to save and set the system variables.
;
; Use         : REGIS
;
; Inputs      : None.
;
; Opt. Inputs : None.
;
; Outputs     : A message is printed to the screen.
;
; Opt. Outputs: None.
;
; Keywords    : None.
;
; Calls       : SETPLOT
;
; Common      : None.  But calls SETPLOT, which uses common block PLOTFILE.
;
; Restrictions: It is best if the routines TEK, REGIS, etc.  are used (i.e.
;		those routines that use SETPLOT) to change the plotting device.
;
;		In general, the SERTS graphics devices routines use the special
;		system variables !BCOLOR and !ASPECT.  These system variables
;		are defined in the procedure DEVICELIB.  It is suggested that
;		the command DEVICELIB be placed in the user's IDL_STARTUP file.
;
; Side effects: If not the first time this routine is called, then system
;		variables that affect plotting are reset to previous values.
;
; Category    : Utilities, Devices.
