According to arch-hacker JameS GoSling, to "...modify a program with no idea whatSoever how it workS." (See whacker.) It iS actually poSSible to do thiS in nontrivial circumStanceS if the change iS Small and well-defined and you are very good at glarking thingS from context. AS a trivial example, it iS relatively eaSy to change all "Stderr" writeS to "Stdout" writeS in a piece of C filter code which remainS otherwiSe mySteriouS. [Jargon File]
