Brent,

Thanks for the report. I see where the problem is. This became broken when some changes were made to allow a component count > 2*32. Not a likely scenario, but it followed through with extending things as far as we could. The code to convert a 32 bit integer file system argument to a 64 bit integer argument didn't handle sign properly and so it looked like the count was way bigger than the existing number of components.

I have a fix. I'm not sure when it will go into a build.

/Mark

This problem is fixed in the APL+Win version 5.2.03 beta.

[]CFDROP works OK in v5.2.03. But many native files system functions are broken.

Sigh. Yes, the CFDROP fix and the NF-fns bugs are related. I will fix it shortly, but a build will probably not be forthcoming until sometime next week. /Mark
