readcol problems [message #49493]

I'm pretty new to IDL and don't know much about it.

I'm trying to use the readcol function but I keep getting errors
"variable
is undefined", "attempt to call undefined procedure/function:
'NUMLINES'"
and sometimes it can't seem to find my .dat file. I'm guessing I must
be
missing some horribly obvious line to get the "variable undefined"
error
but I don't know why I keep getting the Numlines error. I don't need it
to count the number of lines, I just want to plot x against y.

I'm using a windows version and this is the code I'm using:

PRO test, x, y

readcol, 'test.dat', x, y, f='f,f,'

plot, x, y, psym=2

END

Any help would be greatly appreciated. :)
