I was recently following a post where a user asked what the earliest SAS PROCs (procedures) were. Since I started using SAS in 1970, I knew I could find a copy of the old documentation that we used at that time. This “user’s guide” was something that you printed out on an old line printer on regular computer paper.
I did find the guide. And the list of procedures in SAS at that time brought back some good memories. By the time I found the old guide, Chris Hemedinger had already responded to the user on Facebook, but hey, he doesn’t go back as far as I do (most people don’t!). So, here is the list of PROCs documented in the 1970 SAS User’s Guide:
- PROC REGR - regression
- PROC ANOVA - analysis of variance
- PROC FACTOR - factor analysis
- PROC AOV - alternate analysis of variance (treats missing values as zero; not as efficient as ANOVA)
- PROC LATTICE - analysis of variance with three types of analysis (square balanced, square unbalanced, rectangular)
- PROC DUNCAN - Duncan’s multiple range test
- PROC PLAN - randomized plans
- PROC CORR - bivariate statistics
- PROC SORT
- PROC MEANS
- PROC NESTED - nested analysis of variance
- PROC PRINT
- PROC FREQ
Here is Chris Hemedinger's response to the user.
Anyone go back farther than that???
