Identifying programming language

wish of those help Can anyone identify this programming/scripting language off of a few examples of the syntax? It appears each file (function?) starts with: , I have determined that this is in fact proprietary.

hop of those help? You have a problem of document classification. I suggest you read about naive bayes classifiers and support vector machines. In the articles there are links to libraries which implement these algorithms and many of them have C++ interfaces.

hope this fix your issue I think you're approaching this from the wrong viewpoint. From your description, it sounds like you are building a classifier. A good classifier needs to discriminate between different classes; it doesn't need to precisely estimate the correspondence between the input and the most likely class.
Practically: your classifier doesn't need to assess precisely how close to C++ a certain input is; it merely needs to determine if the input is more like C than C++. This makes your work a lot easier - most of your current "unknown" cases will be close to one or two languages, even though they don't exceed your basic threshold.

may help you . Found the equivalent command finally within IPL. The h command selects the Printhead Loading Mode.

I wish this helpful for you In a relational/SQL database it makes no practical difference. The identifying / non-identifying concept exists in ER modelling primarily as a way of explaining semantic aspects of the business domain, i.e. business rules about the preferred means of identification and mandatory relationships between entities.
There also exists a practice among some ER modellers that referencing attributes (i.e. "foreign keys") are shown on a diagram only when they are also required for identification purposes (i.e. "primary key" attributes). When the references are "non-identifying" the theory goes that they are implied by the existence of a relationship line and don't need to be shown in the referencing entity at all. That convention rarely seems to be observed these days (at least in my experience) but it may explain why the supposed significance of identifying relationships came about.
