Now that you brought that up, Nic, I knew Pascal and Basic really well, and had a semester of assembly language and COBOL, but most of that was nearly 30 years ago!
As far as spoken languages go, no. I am not fluent in any language and can barely wing it in ASL. I know some words in Spanish (can recall numbers to billions, though), some words in Saṃskṛtam (Sanskrit), and one phrase in Arabic. I, however, created my own language to deal with the frustration in learning languages, which is called Galeh Yuvo. Look at my avatar under my name, and that is my language. I use it to hide information from people in plain sight and as spiritual practices, in which I sometimes combine Sanskrit words within Galeh Yuvo sentences.
