Access variables inside a - piped while - loop

Consider the following simple situation [ reading something using while and read ] [See script 1 in sample output] --------------------------------------------------- The variable var is assigned with "nullll" at first. Inside the while loop [piped while] it is assigned with "whillleeee". [Onlly 2 assignments stmts]. Outside the loop the last assigned value for "var" [and no variable] inside the while can't be accessed [Due to pipe, var is executed in a sub shell]. In these type of situation variables can be accessed by modifying as follows. [See script 2 in sample output] ___________________________ Vary helpful when reading a set of items, say file names, stored on a file [or variable] to an array an use it later. Is there any other way 2 access variables inside and outside the loop ?? Show Sample Output

I hate `echo X | Y`

apart from not being generalisable to all shells, `Y <<< X` seems nicer to me than `echo X | Y`, e.g. $ <<< lol cat; it reads easier, you type less, and it also looks cool
