I remember from GW-BASIC there being, ERR, ERL, CSRLIN, and probably a few others. C64 BASIC V2.0 had ST and TI/TI$.

BASIC's version of $RANDOM is RND(x), and I remember that the sign of the argument was the most important thing. Negative values seeded the PRNG and any positive argument got you the next random number. Some later dialects had a RANDOMIZE statement.

The funny thing is BASIC also had a couple functions that took input variables, but didn't do anything with them, like POS() and FRE(). I think FRE's argument may have been significant on a couple BASICs.
