Latex preamble with TexMaker

[codymk39]

Hi,
thanks for all your hard work.
I have been trying to view some mcad15 files and found your parser most helpful.
In order to view the output of your parser as a pdf with Texmaker, (and /or texlive, MikTex) I found it necessary to add the following:
(I am very, very new to LaTex and I am an old fortran/C programmer I do not speak Python, please excuse any extra ignorance...)
I changed/added to from:
\documentclass[10pt,a4paper]{report}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}

to

\documentclass[10pt,a4paper]{report}
\usepackage{textgreek}
\usepackage[utf8]{inputenc}
\usepackage[LGR,T1]{fontenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}

The output then formatted and displayed.
the LGR flag for fontenc was of first importance, then the textgreek addition.
As the use of greek symbols is very common in mathematics and physics I thought you might want to know. My spreadsheets are a mixture of math and physics. Thanks again.
