FOR statement

[Eli Beckerman <ebeckerman(at)cfa.harvard.edu>]

Hey,

I just tried running a FOR loop in the hopes
of incrementing the variable "i" by steps of 0.25 as follows:

radius=fltarr(1000)
FOR i=0.0, 100.0, 0.25 DO BEGIN

  radius(i)=i

ENDFOR


And what I end up with is an array that starts
with the value 0.75 and is incremented by steps of 1.

I'm following the convention of the FOR statement as
presented in IDL's online help. What am I doing wrong?!


Cheers,
Eli
