Having had no response to my inquiry concerning a possible bug in the 
filevalid opcode (see message below), I'm assuming that it will not work for 
my purposes.

In addition, for several reasons, I'd like to use such an opcode in versions 
of Csound predating 5.13 (the first in which filevalid appears).

So, does anyone know of a filevalid-style *UDO* (or could anyone construct 
one for me) that accomplishes the following more limited objectives:
1) searches only the current directory;
2) searches only soundin.x files (with x being the input parameter to the 
UDO)
3) (optionally) runs at k-rate (I *can* presumably put the UDO into a 
reinitialization routine if necessary; I'm already doing that with filelen)

This needs to work cross-platform.

FWIW, I'm not convinced that a UDO is possible here; the cross-platform 
requirement may well rule it (and the system opcode) out. If that's the 
case, it seems even more important that the apparent filevalid bug 
(limitation?) be corrected.

As they say... works for me (in old parser).  There is a problem with the
new parser I think, but with your code

SECTION 1:
new alloc for instr 1:
Audiofile does exist!
B  0.000 ..  1.000 T  1.000 TT  1.000 M:  0.00000  0.00000


and also works with does not exist
