* Look for a radial digi near a specified point *
* *
* NB The FRRE bank must have been unpacked into FRLC and FRHC, with *
* a pointer to FRLC in INDLC(2) in /FFGEO/ *

*KEEP,FKNPL.
*
* Per-track values can go in H1WORK; note that LTRUE and LFIRST must
* be set at least per event.
*
* This is about 36k words long; the remaining common blocks are
* about 3.6k in total. Some of this could be in /H1WORK/, but the
* blocks would have to be reorganised.

INDHC = NLINK('FRHC',0)
* Check for dead wires
*
* Find the hit with the minimum difference between its drift and
* the target drift. Since the resolution is 150 um and the two-track
* resolution is 2 mm there is never any ambiguity; also no need to
* look at the radius.
*
* Check that it's the right wedge, and the hit is OK
