After having removed ALL the <CR>s from both files, this seemed to work:
Code:
. /tmp/propertyfile.txt
while read KW
        do eval echo "$KW${TMINRECORD:0:1}{${TMINRECORD:1}..${TMAXRECORD:1}} $KW${KMINRECORD:0:1}{${KMINRECORD:1}..${KMAXRECORD:1}}"
        done < /tmp/File1.txt | tr ' ' '\n'
00123T10
00123T11
00123T12
00123T13
etc...

Can u please explain the code. I'm getting bad substitution error. i think eval command is not working.

I failed to mention that this needs a recent shell capable of brace expansion. A recent bash can do it out of the box, ksh needs the -B option set (afaik).

bash-4 will even retain the 00..04 (bash-3 will reduce to 0..4).
The following lets printf fold to lines:
Code:
#!/bin/bash
. propertyfile.txt
while read KW
do
  eval printf '%s\\n' $KW${TMINRECORD:0:1}{${TMINRECORD:1}..${TMAXRECORD:1}} $KW${KMINRECORD:0:1}{${KMINRECORD:1}..${KMAXRECORD:1}}
done < File1.txt

But still the eval is the evil.

I'm using KSH. I tried the above code and its not working. Any other solution?

ksh93 does it like bash-3. You seem to have the older ksh88.
Here is a solution with awk:
Code:
awk -F"=" '
NR==FNR {s[nn++]=$2; next}
{
  for (n=0; n<nn; n+=2) {
    letter=substr(s[n],1,1)
    startd=substr(s[n],2); endd=substr(s[n+1],2)
    lend=length(startd)
    for (d=startd; d<=endd; d++) printf "%s%s%0*d\n",$0,letter,lend,d
  }
}' propertyfile.txt File1.txt

On Solaris, take nawk or /usr/xpg4/bin/awk
