Python script that uses LLMs on Groq to create Fortran programs, iterating with compiler error messages until they compile. All attempts are saved,
with names such as foo1.f90, foo2.f90 etc. It has been tested on Windows but may run on other operating systems. It works with ifx as well
as gfortran, with a suitable value for compiler_options. I created analogous scripts for C++ and Python.

where the prompt_cauchy.txt contains
Do a Fortran simulation to find the optimal trimmed mean estimator of
the location of the Cauchy distribution, trying trimming proportions
of 0%, 10%, 20%, 30%, 40%, and 45%. Declare real variables as
real(kind=dp) with dp a module constant, and put procedures in a
module. Have the simulation use 100 samples of 1000 observations each.
sample output is
Attempt 1 failed (error details suppressed, generation time: 3.164 seconds, LOC=67)
Attempt 2 failed (error details suppressed, generation time: 14.672 seconds, LOC=71)
Code compiled successfully after 3 attempts (generation time: 18.061 seconds, LOC=75)!
