thanks friend for help

i have read many books and i read yet the last i try to study is The Complete Reference Unix" from Obserne

one thought is wrote this code to replace the '-' with right character is using the substr
is using this code to calculate the length
Code:
wordlength=${#word}
awk -v var1=$charact 'BEGIN {for (i=1;i<=wordlength;i++){A[i]=substr(var1,i,1)};for (i=1;i<=wordlength;i++){print i,T[i]}}' /dev/null

do you believe that may work or what you recommend to chance in this code to run correctly

using this code i split the word to a table

Code:
awk -v var1=$word 'BEGIN {FS="';split (var1,T); (for i=1;i<=length(var1);i++) {print i,T[i]}}' /dev/null

using this code i replace the characters with - - -
for example if the word was bedroom with this code appear - - - - - - -
Code:
awk -v var1=$word 'BEGIN {for (i=1;i<=length(var1);i++) {printf("%s","-")};print}' /dev/null

i want to read a character using this command
Code:
read charact

and if this character included for example to bedroom display this character for example

the word is :bedroom
script appear: ------- 7- depends on word length
while i read charact: press e
i want the script appear this -e----m

i think i can do that with substr

i use bash

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

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
