Preferred calculator program language

[Joe Horn]

For me, it depends on the simplicity of the task being programmed. If what's needed is a quick-and-dirty routine for cranking out something relatively simple, then either RPL (which I *think* in) or RPN keystroke programming (e.g. FOCAL) are my favorites. But if the task is a large, complicated project, where huge-source-code readability and maintainability are vital, then the programmer-friendliness of higher-level languages becomes more valuable than the speed with which quick-and-dirty routines can be thrown together in RPL or FOCAL. HP-71 BASIC with a few structured-programming lexfiles added (e.g. the JPC ROM) and HP PPL are my favorites for large jobs.
