try with awk. Use the substr($0,Starting_Position,Length) function to cut specific byte from the file.

e.g.
111333xx444TTTLKOPxxxxxxxxx


awk '
{
filler1=substr($0,0,3)
fild1=substr($0,4,2)
filler2=substr($0,6,8)
fild2=substr($0,15,2)
filler3=substr($0,17,11)
printf("%s%s%s%s%s",filler1,fild1,filler2,fild2,filler3)
}' file1 > out_file

Note: Adjuct the filed position as per your correct file layout.

Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSuUser(Contributed Perl DocumPerl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr(3)

NAME
Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr - Use 4-argument "substr" instead of writing "substr($foo, 2, 6) = $bar". AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
Conway discourages the use of "substr()" as an lvalue, instead recommending that the 4-argument version of "substr()" be used instead. substr($something, 1, 2) = $newvalue; # not ok substr($something, 1, 2, $newvalue); # ok The four-argument form of "substr()" was introduced in Perl 5.005. This policy does not report violations on code which explicitly specifies an earlier version of Perl (e.g. "use 5.004;"). CONFIGURATION
This Policy is not configurable except for the standard options. SEE ALSO
"substr" in perlfunc (or "perldoc -f substr"). "4th argument to substr" in perl5005delta AUTHOR
