         /Cross-talk/           {L=0}
         /Number of/            {NoS=$NF}
         L && / \+ \(/          {SoL=NR; EoL=NR+NoS-1}
         NR<=EoL                {sub (/\)/,_); TM[NR-SoL]=$(NF-1); DT[NR-SoL,RCnt]=$NF/NoS}
         END                    {for (i=0; i<NoS; i++)
                                        {printf "%14.8E", TM[i]
                                         for (j=1; j<=RCnt; j++) printf "\t%14.8E", DT[i,j]
                                         printf "\n"
                                        }
                                }

Hi RudiC,

Thanks for your reply! Your code is far neater than mine. I have to spend some time on understanding it first.

Thanks,

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
