window, and how to assign that bit of code to a key or toolbar button.
readdata.sas Code to read data into SAS
in various ways
tomrand.sas Code to do a two-sample
randomization test using PROC NPAR1WAY with SCORES=DATA.
tomt.sas Code to do a two sample t-test
using PROC TTEST.

test in either PROC MEANS or PROC UNIVARIATE. PROC MEANS also
computes confidence interval for mean difference. PROC UNIVARIATE
also computes the nonparametric sign and Wilcoxon signed rank tests.

variables and construct a residual plot using proc glm.

nonparametric 2 sample test (Wilcoxon rank sum test).

the ANOVA table, calculate group means, and test linear combinations

set up and fit intermediate models.
