>Why *do* people want to stick 'fmt', or worse 'format' into the names of formats,

I work with a lot of secondary datasets which have hundreds to thousands of variables with differing formats, and I have to pass my code to a variety of people who may want to use it in nefarious ways. The easiest way to remember and work with the formats, is to append an f at the end of the variable name. It is easy to comment and convey what is happening. To simply reuse the variable name creates potential confusion; to invent new names stretches my creativity, and requires lookups. While context and periods point out what is a format versus what isn't, a missing period has different implications based on whether what remains is a defined or undefined variable.

consider format aaa aaa bbb bbb.;

versus format aaa. aaaf bbb bbbf.;

The first generates no errors or warnings (at least in 8.2). The second still requires that you look at the log, but I try my hardest to get people to glance through them. The list _output_ doesn't always make clear that the wrong format has been applied.

Beats me. It's always clear from context whether a word is a format name or something else, and almost always clear just from the word alone (a format name almost always contains a period, and almost no other token ever does, at least not in base SAS - the only exception I can think of is a summary variable inside a compute block in PROC REPORT).

I suppose it's a symptom of not knowing SAS very well.
