as/c a z1

This works by creating a string of infinite length. as /c Sets an alias (here called a) to the result of the following command(s): z 1 is an infinite do while loop that also prints a line when the while condition is true: redo [###] {redone_code}. So a will be set to a string like:

redo [1] z1
redo [2] z1
redo [3] z1

redo [23489723984] z1
