When I run RudiC's code with a file containing:
Code:
XXXXXXX XXXXX                 MM11111    ZM    0         000000000000000000000OREGON XXXXXXX HXN  001111  01010

and the parameters POS="48-51" and the name of the file containing the above text, I get the output:
Code:
XXXXXXX XXXXX                 MM11111    ZM    0000      000000000000000000000OREGON XXXXXXX HXN  001111  01010

which would seem to produce what you want in a manner similar to the example you provided in post #1 in this thread (without shifting any other data around).

Are you saying that you have changed the format of your input data such that the number in the field you are zero-filling is right justified instead of left justified as it was in your original sample input???

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
