      for(i=1;i<length(F);i++)N[substr(F,i,1)]=substr(T,i,1);
    }
    NR == 18 {
      out=x
      for(i=1;i<length;i++) {
         c=substr($0,i,1)
         out=out (i>10&&(c in N)?N[c]:c)
      }
      $0=out
    }
    1
' infil



Based on ur code

the output is

NM1*IL*1*LBMXSDROORZNNRI97914


Where the * ( stars) ? it should be unchanged .. alpha should be alpha and numbers should be numbers.

sorry to bother you again. Do you have any restriction in your code on maximum length in file

My input

N3*PO BOX 4703


ouput is

N3*KL YLC 529


Note : in this im converting from 4 th position to rest of the line

Code:
awk  -v k3="$k3" '
    BEGIN{
      F="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"
      T="ZYXWVUTSRQPONMLKJIHGFEDCBAzyxwvutsrqponmlkjihgfedcba9876543210"
      for(i=1;i<length(F);i++)N[substr(F,i,1)]=substr(T,i,1);
    }
    NR == k3 {
      out=x
      for(i=1;i<length;i++) {
         c=substr($0,i,1)
         out=out (i>3&&(c in N)?N[c]:c)
      }
      $0=out
    }
    1
' $file

Many versions of awk limit the length of a line to LINE_MAX bytes. The value of LINE_MAX on your system can be found using getconf LINE_MAX). But it looks like there is an off by one error that is causing your problem here. Try changing:
Code:
      for(i=1;i<length;i++) {

to:
Code:
      for(i=1;i<=length;i++) {

Moderator's Comments:
Mod Comment Please use CODE tags. Trying to line up input and output is hard enough without the problems caused by variable width fonts used outside of CODE tags.

So there were two off by one errors. Also change:
Code:
      for(i=1;i<length(F);i++)N[substr(F,i,1)]=substr(T,i,1);

to:
Code:
      for(i=1;i<=length(F);i++)N[substr(F,i,1)]=substr(T,i,1);
