The Icon programs in this directory are constructed from files of Icon expressions, using the program buildt.icn. For example, to create a new test program testx.icn from the list of expressions in testx.inp, buildt testx.icn A general framework is put around each program to facilitate testing of records and such. See any file produced by buildt.icn for an example. There is complementary program, dismem.icn that takes test programs build by buildt.icn and produces the corresponding list of expressions, as in dismem testx.inp
