But, back in the day, if you wanted to add functions to MATLAB, you would add them in FORTRAN 66, and rebuild the MATLAB interpreter. Microsoft BASIC-80 (around the same time) was written in assembler. You also don't write in assembler when using BASIC-80. But, BASIC-80 would be extended by assembler, in the same way that MATLAB would be extended by FORTRAN.
