I simply use the following:

PRO Sao, image, verbose=verbose

On_Error, 2 ; return to the caller of the
function

IF ( N_params() NE 1 ) THEN message, 'Syntax - sao, image, [/verbose]'

imsize = size(image)
IF ((imsize(0) GT 2) OR (imsize(0) EQ 0)) THEN BEGIN
message, 'Image does not have the correct dimension'
ENDIF

IF (imsize(0) EQ 1) THEN BEGIN
image = reform(image,sqrt(imsize(1)),sqrt(imsize(1)))
ENDIF

options=''
IF n_elements(verbose) NE 0 THEN BEGIN
options=options+' +v'
back=''
ENDIF ELSE BEGIN
options=options+' -v'
back=' &'
ENDELSE

writefits, 'saotmp.fits', image
spawn, '(saoimage'+options+' -ll -zero -fits saotmp.fits; rm -f
saotmp.fits 2>/dev/null)'+back

END
