Where should a validation suite come from with such old code? There are numerous examples, partly from the accompanying text books, partly generated by myself by reverse engineering the source code, where I even found a number of bugs in the published code, as well as some quirks such as PRINT also being accepted as PRONT, due to incomplete decoding of keywords. The examples do work, but there is no warranty that it will be bug free under all circumstances. Take it or leave it as is. Holger
