Loop Through

/lüp thrü/

vt. To process each element of a list of things.

"Hold on, I've got to loop through my paper mail."

Derives from the computer-language notion of an iterative loop; compare 'cdr down' (under cdr), which is less common among C and UNIX programmers. ITS hackers used to say 'IRP over' after an obscure pseudo-op in the MIDAS PDP-10 assembler.
