If you don't want the 'ABC' included in the filenames then you'll need to use $1 rather than $0 (and removing the spaces won't be necessary). Using gsub rather than substr to extract the filename is probably a better idea as well - since it's not a fixed-length string.

Well, what you actually seem to want is the rest of that field, not the next 10 characters.

Similar to ahamed101's earlier suggestion:
Code:
a=gsub("FILEHEADER","",$1)
