 1001! SRCNAM = 01001  !
    1! X =  50.0000,  0.0000, 25.0000,0.2279E-07,0.0000E+00,0.3697E-07,0.0000E+00,0.0000E+00,0.3212E-08,0.4051E-10  !  !END!

Thanks. I thought of doing this exact command, but I would need to loop from SRCNAM = 00001 to SRCNAM = 01001 and I wasn't sure if this was possible. I know I could loop from SRCNAM = 1 to SRCNAM = 1001, but the leading zeros complicate what I am trying to do.

Instead, is there a similar sed command that could specify the range of the placement of characters to change?

i.e.
Code:
 sed -n 1p| sed 's/^.\(....\)\(.*\)/\1001\2/g'

Or alternatively try awk?
Code:
awk '{$1+=1000} /SRCNAM/{sub(/[0-9]+/,0 $1,$2)}1' FS=\! OFS=\! infile
