i'm read help again for ENVI_GS_SHARPEN_DOIT
in help showing that LORES_FID = array !
Syntax
ENVI_DOIT, 'ENVI_GS_SHARPEN_DOIT', DIMS=array | FID=fileID [,
/FILTER_FID=variable] [, HIRES_DIMS=array], HIRES_FID=fileID |
HIRES_POS=array | /IN_MEMORY [, INTERP={0 | 1 | 2}] [,
/LORES_DIMS=array] [, LORES_FID=array] [, LORES_POS=array] [,
M_FID=fileID] [, M_POS=array] [, MASK_VALUE=value], METHOD={0 | 1} [,
OUT_BNAME=string array], OUT_NAME=string | POS=array [, R_FID=fileID]
yes i can do pan sharpening through ENVI menu with same data files

Have a closer look at the help for ENVI_GS_SHARPEN_DOIT. The LORES_FID
keyword wants a long integer. You are passing it an array. I don't think
you should use this keyword at all if you are using METHOD=0. Again,
read the help carefully.
Can you do the pan sharpening with the same input data from the ENVI menu?

Hello,
You define the hi_res_dims array but you don't pass it to the batch
routine with the HI_RES_DIMS keyword. The keyword is optional, but it
might nevertheless be necessary for your images.

I'm afraid that that must be a misprint. If it is a file ID, it can't be
an array. Look at the explanation for the keyword later in the online help:
LORES_FID (optional)
Use this optional keyword to specify the file ID for the low spatial
resolution panchromatic file. You must specify LORES_FID if METHOD=1.
This value is returned from the keyword R_FID in the ENVI_OPEN_FILE
procedure. LORES_FID is a long integer with a value greater than 0. An
invalid file ID has a value of -1.
As I said, I don't think you need it for METHOD=0.
