How to make dynamic variable names for use in while loop?
Code:
i=0
while [ $i -lt $numberofproducts]
do

sizesfor0=`cat 16 | grep 'pickSize' -A 1 | grep '_sz' | cut -d'_' -f1`
sizesfor0=${sizesfor0//id=\"lll/:}
IFS=: array0=( $sizesfor0 )
echo ${array0[1]}
 i=$(( $i + 1 ))

done

So, right now I have two variables in the while statement above

sizesfor0 and array0

The above statement works, but it is hard-coded with the 0 suffix, how does one turn the above variables into sizesfor$i and array$i so that I can add 1 after each iteration to make the while loop functional?

I've tried doing exactly that, (changing to sizesfor$i and array$i) but there are compatibility issues.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
