Thanks Franklin52 for your reply. I tried both but still get the error:

bash-2.05$ returncode=`cat imp_619015_5.txt | awk '{print substr($1,1,2)}'`; echo KSC_EXIT_STATUS $?
received echo:
returncode=`cat imp_619015_5.txt | awk '{print substr($1,1,2)}'`; echo KSC_EXIT_STATUS $?
awk: cmd. line:1: {print substr($1,1,2)}
awk: cmd. line:1: ^ Invalid char ' in expression
KSC_EXIT_STATUS 2
Command: [returncode=`cat imp_619015_5.txt | awk '{print substr($1,1,2)}'`] did not complete successfully.
Aborting command execution.
Closing telnet session.
Errors occurred during command execution.

I wonder if there is something corrupt with the bash or cygwin on the server?

Thanks,
accsam1

perl::critic::policy::builtinfunctions::prohibitlvaluesubstr

Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSuUser(Contributed Perl DocPerl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr(3pm)

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
