# Programming Language History

Well... this is not easy stuff. As proof of that statement, look at computer history. It took several decades before modern high level languages were established. The first one of any importance was Algol, created about 1960. Algol established stack-based subroutine linking. But Algol never quite caught on.

Pascal (created about 1974) was a milestone. It became highly popular and used this stack-based idea of subroutines (which it called procedures and functions). Programming languages can be classified as "Before Pascal" and "After Pascal."

But let us return to the MIPS processor (created in the year 10 AP).

### QUESTION 10:

Is the MIPS instruction set (its machine instructions) optimized for subroutine call and return?
