Thks for the help. I finally applied it succesfully today.

But, here comes another seperate but related problem. This time, I tried to convert from a Hex to Deci number by creating a new script with "%d" on the hex number, but it failed.

I need to convert a file with these,

ABC c001 DEF
ABC c050 EFG
ABC c802 GHI

to

ABC 49153 DEF
ABC 49232 EFG
ABC 51202 GHI

Please help me again.
Thank you!!
