Thanks for the detailed explanations of *declare *.

As to the idea behind of my request:
1) I need local variable RESULT as empty string (not array)
2) this RESULT should collect symbols taken from other strings using
${STRING:i:1} for one symbol or ${STRING:i:k} for k-symbols
So, the main question is: how to save such sub-strings in RESULT at needed
j-place?
With another words - I need RESULT as C-char-array to use it something like
this

RESULT[j]="${STRING:i:1}"

In good examples of my bug.bash file there was used kind of accumulation
data in RESULT

RESULT="$RESULT${STRING:i:1}"

What about saving data in the direct place of the RESULT-string?
After your explanations, bash-arrays are not for such actions (my words -
do not work) :(
And a way to accumulate data in RESULT is the only possible in BASH.
What is your opinion or more suggestions?
Thanks
