Processing about 10,000 tif files [message #90976]

Dear Gurus,

I have RGB images in tif format and want to do simple arithmetic calculations.
A big obstacle to me is number of files to be processed, about 10,000 images.
Name of the image files has sequential id such as img_1.tif, img_2.tif, ....., img_10000.tif.
And I have a text file containing image names, coefficients, and offsets.
I think reading the text file as an array with three columns and lines matching number of files seems to be successful.

I've tried to read image files with dialog_pickfile, but I've learned that the function limits byte length and can't seem to go beyond more than 2,000 files or so.
And I've tried to read image files with file_search, but it didn't do calculation in sequential order.

Would you give some suggestion how to read image files in order, so that following calculation should be in order from 1 to 10,000?
Or a way to do calculation with image name corresponding lines in the text file?

Thanks in advance,
Kim
