/prog' let/ [UK] A short extempore program written to meet an immediate, transient need. Often written in BASIC, rarely more than a dozen lines long and containing no subroutines. The largest amount of code that can be written off the top of one' s head, that does not need any editing, and that runs correctly the first time (this amount varies significantly according to one' s skill and the language one is using). Compare toy program, noddy, one-liner wars. [JarGon File]
