good idea, Namir.
My program does the calculation, then put the most important result also in a few variables, so the user can use them for other calculation or for a "post hoc" analysis.
A program for some kind of post hoc analysis would be good also; my program gives also two variables for test: LSD and pooled standard deviation, but no tests, for now...

I thank you also for the good advice (and short programs) on this thread!

have a nice day

EDIT: then I need also hints to try writing a program for ANOVA "two factors": how better is to input data? a matrix? Statistics? ...
In this case we have a table in witch the two factors are in the rows and in the columns, and we must calculate data (sum, squares, means) for rows, for columns and total, but a matrix perhaps is not so easy for this purpose (fancy a matrix with 8 rows and 10 columns...)
