Yes - I got this error too. The LIST statement should read:

list if (k = k[_n-1]) or (k = k[_n+1])
* if you only want the first of two records to appear:
list if k = k[_n+1]

*** Of course you have to insert some duplicate records into a copy of bromar.rec first ***

|Indeed some of the line breaks threw it a bit. I reformatted below - but 
|still get that strange TRUNC error like:
|. list if k = (( k[_n-1]) or (k[_n+1]))
|Operator TRUNC is incompatible with String
|Operation aborted
