It may be that you have previously used another language which allows a function to be called without assigning the returned value to anything, but Liberty BASIC doesn't. If you want to call a function, but ignore the value it returns, you must assign it to something, for example:
Code: ignoreThis = openRAF(path$,fileName$,fileHandle$,recordLen)

Now, there's a difference between SUB and FUNCTION that I missed. Thanks!

I occasionally use this construction, to avoid creating a dummy variable, but it's a bit ugly (and relies on a 'feature' of LB/LBB that rem and ' are not always equivalent):
Code: if openRAF(path$,fileName$,fileHandle$,recordLen) then rem
