One more point, the routines are in CM mode.

Keven's :SETDUMP will help, if you're aborting.
If you fall into debug, post the results of:
dr
tr,i,d
What language is the code that's calling FREADDIR?
BTW, here's how to set a breakpoint to look at the
parameters:
:cseq FREADDIR
<plug>...you *do* have CSEQ, don't you? :) Every programmer should!
</plug>
Ok, ok...
:cseq freaddir
Procedure FREADDIR (
filenum : int16 ; {R26}
target : anyvar record ; {(skip R25)
R23, R24}
{Address type = LongAddr}
tcount : int16 ; {SP-$0032}
recnum : int32 ) {SP-$0038}
{tcount is > 0 for 16-bit words, < 0 for bytes }
uncheckable_anyvar
The above says "what you called freaddir is actually FREADDIR"
(NM procedure names are case sensitive, BTW).
It also says: the intrinsic has 4 parameters, 3 by-value and
1 by-reference. The reference parameter is an 8-byte long address.
NOTE: the following is for NM programs.
Setting a breakpoint for the CM FREADDIR is done differently!
Since you might have a number of calls to FREADDIR before you
abort, let's write a macro to display the parameters and
automatically continue.
run myprog; debug
macro show_freaddir { /* that's a left brace, not ( or [
wl "FREADDIR (file ", r26:"#",
" to ", r23.r24,
" for ", [s16 sp-$32]:"#",
", rec ", [sp-$38]:"#", ")";
c }
/* NOTE: setting a breakpoint at FREADDIR requires
/* that you, the user, have PM capability
b FREADDIR, , quiet, show_freaddir
c
Example output:
/t t (I'm in QEDIT, texting in a small file)
FREADDIR (file #13 to $84c.418389c8 for #512, rec# 0)
FREADDIR (file #13 to $84c.41a5eb78 for #4096, rec# 1)
'Language' is now DATA
FREADDIR (file #13 to $84c.41a5e2f8 for #4096, rec# 1)
115 lines in file
The above shows that FREADDIR was called three times.
