| It is VERY important to note that the dimensions inside the square brackets "[]" is ONLY guidance for the user and is completely ignored by the parser. It can happen that these indicies get out of sync with the code and so they should be considered questionable and verified with a seeshape (varname[]) whenever you aren't sure. | It is VERY important to note that the dimensions inside the square brackets "[]" is ONLY guidance for the user and is completely ignored by the parser.
