Your DIM location is suspect. I would leave it with each local FN.
However,as you are dimming them currently, if they are global, they are
rendered non-global by Local MODE.  Thus you have to DIM it again.

Not sure of your problem...here is how I  pass an FSSpec as applied to your FN.

LOCAL FN lockFile(theFSSpecRec as ^FSSpec,bool%)
DIM @ ignore as INT
DIM mySpec as FSSpec // use @ if compiler complains.

mySpec = theFSSPecRec

LONG IF bool%
     ignore = FN FSpSetFLock(mySpec)
     ignore = FN FSpRstFLock(mySpec)
END FN = ignore
