Yup, thanks, I've had a bit more time and from looking at the disassembly in 
'Unwravelled' I worked out that the argument is passed in FPA0. Then, 
looking at the section on "Floating Point" I found INTCNV and GIVABF.

Thanks for those references though - no doubt they'll come in useful!

It's frustrating because I'm trying to do some fast bit-manipulation in a 
BASIC program, and I turned to ML to speed things up, only to find that 
BASIC has no concept of INTEGERS and passing values to/from ML is rather 
*S*L*O*W* because of the INTCNV/GIVABF routines... :(
