Looks like you are using the gsub function incorrectly in your awk statement. I feel sed would be the best tool for this job.

Assuming you want your output to look like this (if this is not what you want your output to look like please provide sample output):

Code:
1 Ps 1 ,1 VWB/(J VWB VWB
2 Ps 1 ,1 &WHJ== WHJ HJ==
3 Ps 1 ,1 L L L
4 Ps 1 ,1 GBR/~> GBR> GBR
5 Ps 1 ,1 D D D

You can use the below sed one liner which will work on your input:

Code:
 sed 's/\([0-9]\),/\1 ,/g'  textfile

Reading your post again, it looks like you want your output like this instead:

Code:
1 Ps 1,1  VWB/(J VWB VWB
2 Ps 1,1  &WHJ== WHJ HJ==
3 Ps 1,1  L L L
4 Ps 1,1  GBR/~> GBR> GBR
5 Ps 1,1  D D D

In which case change the sed one liner to this:

Code:
sed 's/\(,[0-9]\)/\1 /g' textfile

igawk

IGAWK(1)							 Utility Commands							  IGAWK(1)

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
