I've got a problem for the HP-48 hackers (or for HP). I'm using C-Kermit on VMS, and I haven't been able to send a binary object from the 48 to VMS and back. My guess is that VMS always sends an object with a multiple of 512 bytes, the block size it uses for binary files. The HP-48 doesn't like this and makes the received object into a string. So here is the challenge: Write an HP-48 program that takes the string, truncates the garbage at the end, and makes it into the appropriate binary object. Is there sufficient information in the string to do this -- particularly to determine the proper length? -- edp (Eric Postpischil) "Always mount a scratch monkey." edp@jareth.enet.dec.com

edp - after your speedy and helpful assistance with VAX <-> HP-48SX
transfers I was hoping I could help with the binary transfer problem.
So far no luck though.
I downloaded MSHOW, Jeff Kuhn's Mandelbrot pattern sampler, using VMS
C-Kermit. The byte count on the VAX was 82. The HP made it a string
object. BYTES said 87. The +5 seems usual for a string; "ABC" gives 8.
Hence I don't think C-Kermit is sending too many bytes. There must be
some other reason for the HP making it a string.
