These tutorials were updated in April 2023. The two versions offered--M.S. Office and PDF--are identical except that the four programing examples contain animation effects in the Office versions that do not carry through to the PDF versions. (The PDF versions are not missing any info... just missing the animations.) For both formats you can download either individual tutorials or a ZIP package containing the entire collection. (No need to get both!) You can also download a single PDF document combining all individual tutorials. B. Semenov April 9, 2023
