uFortran – The mother of all mathematical modeling languages (1956)
uAlgol – influenced C’s development (1960)
uGPSS – IBM’s General Purpose System Simulator (1961)
uDynamo – used first for USAF logistics
uAPL – A Programming Language – all mathematical symbols.

• The languages list above (Araten, 1992) was developed for the purpose of solving complex mathematical problems.  I  personally wrote air cooled heat exchanger simulations in the IBM MVS/TSO environment.  Card deck images were created and read by the SYSIN statement of the batch environment using JCL.   The output was sometimes hundreds of pages long.  As far as a Human Computer interface, if a card deck was an interface, then I guess we had one.  Current students would not know what the cards looked like.
•APL was another programming language that was strange in it’s interface.  It only had mathematical symbols and required a special keyboard.
