chr1 201 299 2.txt
chr2 800 1000 2.txt
chr2 100 200 2.txt
chr3 500 600 2.txt

Please, no offense. Since the earlier replies in that post worked, I didn't want to bother Shell_life.
If you had noticed, I made the two file names as variables for the shell.

This way, to have your desired output, you just run it twice:
1)
Code:
mF1='1.txt'
mF2='2.txt'

2)
Code:
mF1='2.txt'
mF2='1.txt'

Here is the same solution again:

Code:
#!/bin/ksh
typeset -i mFromA mToA mFromB mToB
mF1='1.txt'      ### <======= Change file name here (I)
mF2='2.txt'      ### <======= Change file name here (II)
mPrevTag=''
#### sort is used to reduce the number of "grep"
sort ${mF1} | while read mTagA mFromA mToA; do
  if [[ "${mTagA}" != "${mPrevTag}" ]]; then
    grep "${mTagA}" ${mF2} > ${mF2}.tmp
  fi
  mFound="N"
  while read mTagB mFromB mToB; do
    if [[ ${mToA} -ge ${mFromB} && ${mFromA} -le ${mToB} ]]; then
      mFound="Y"
      break
    fi
  done < ${mF2}.tmp
  if [[ "${mFound}" = "N" ]]; then
    echo ${mTagA} ${mFromA} ${mToA} ${mF1}
  fi
  mPrevTag=${mTagA}
done

       - provide truth value about processor type

SYNOPSIS

DESCRIPTION

       The following commands return a true value (exit code 0) if the a processor type matches the command name.  Otherwise a false  value  (exit
       code  nonzero)  is returned.  These commands are commonly used within makefiles and shell procedures to improve portability of applications
       (see make(1)).

EXAMPLES

       Given a shell script that must behave differently when run on an HP 9000 Series 700 or 800 system, select the correct code  segment  to	be
       executed:

WARNINGS

       always  returns	true on both Series 800 and Series 700 systems.  Therefore, when using this command in scripts to determine hardware type,
       always use both and in the appropriate sequence to ensure correct results (see

       machid(1) will no longer provide support for future machines beyond the Series 800 and Series 700 systems.  Decisions should  be  based	on
       the hardware and software configuration information returned by getconf(1).
