Reads in only part of file

*To*: mathgroup at smc.vnet.net*Subject*: [mg51155] Reads in only part of file*From*: Steve Gray <stevebg at adelphia.net>*Date*: Wed, 6 Oct 2004 04:34:50 -0400 (EDT)*Sender*: owner-wri-mathgroup at wolfram.com

I have a binary file of 945 coordinates, in X,Y pairs, each value being 8 bits, for 1890 bytes total. I have examined the file with a hex file display and editor (which shows the file as 2 hex characters per byte) and confirms that the file contains exactly the expected number of bytes. My input process is: roswin[nv_]:= Module[{st1}, nverts = nv; st1="D:\Math\Geometry\Combinatorial Geom\Oswin\Otypes\otypes07.b08"; Print["Reading file: ",st1]; xin=ReadList[st1,{Byte,Byte}]; ] The file opens ok but the input list xin contains only 230 coordinate pairs (byte pairs) instead of 945. The values that do read in are correct. The {Byte,Byte} seems to be the only data type that works here. Can anyone suggest what I am doing wrong? (Do I have to Close st1?) Thank you for any tips.
