Code:
FNR == 1        {FILENR++
                }

FILENR <= 2     {CHFM = CHFM DL $1
                 RGEX[$1] = $2
                 DOTS[$1] = $3
                 FMTS[$1] = $4
                 FIDX[$1] = FILENR
                 DL = "|"
                 next
                }

                {printf "%s", $0
                 for (j=4; j<=5; j++)   {TMP = $j
                                         PTR = 0
                                         while (match (TMP, CHFM))      {MTCH = substr (TMP, RSTART, RLENGTH)
                                                                         printf "|%s|%s|%s|%s|%s", PTR + RSTART, RLENGTH, MTCH, DOTS[MTCH], FMTS[MTCH]
                                                                         TMP = substr (TMP, RSTART+RLENGTH)
                                                                         PTR += RSTART + RLENGTH - 1
                                                                         TYP[j-3,FIDX[MTCH]]++
                                                                        }
                                        }
                 for (j=1; j<=2; j++) printf "|%s|%s", TYP[j,1]+0, TYP[j,2]+0
                 print ""
                 split ("", TYP)
