GAUSS variables are of two types: matrices and strings.

1. Matrices may contain numerical data or character data or both.

2. Strings are pieces of text of unlimited length. These are used to give information to the

user. If you try to assign a string value to an element of the matrix, all but the Ö rst eight

characters will be lost.

Variables need to have names to reference them. Acceptable names for variables can contain

alphanumeric data and the underscore _ , and must not begin with a number . Reserved words

may not be used standard procedure names may be reassigned, but this is not generally a good

idea. Variables names are not case-sensitive.

1. Acceptable variable names: eric Eric eric1 eric_1 _eric1 _e_r_i_c

2. Unacceptable variable names: 1eric 100 if (reserved word) delif (GAUSS procedure -

legal, but foolish)
