You are missing some essential keywords. Here is a modified version of
your code which works OK for me (uses METHOD=0). I used ENVI_SELECT
because my pan images are too large to be read in in one chunk. You can
modify the code to get back to what you want. But watch the keywords!!

-Mort

; get MS image
envi_select, title='Select MS input bands', $
fid=fid_src_mul,dims=mul_dims,pos=pos_mul

; get PAN image
envi_select, title='Select panchromatic image', $
fid=fid_src_pan,dims=pan_dims

ENVI_DOIT,'ENVI_GS_SHARPEN_DOIT',FID=fid_src_mul, $
DIMS=mul_dims, $
POS=pos_mul, $
METHOD=0, $
OUT_NAME='D:\temp\test.img', $
INTERP=0,$
HIRES_FID=fid_Src_Pan, $
HIRES_DIMS=pan_dims

end
