  First get my adapted Terminal class (Terminal.java) here:
  
  (rename your Terminal.java to Terminal.org) then copy my Terminal.java to the core folder.
  
  http://groups.yahoo.com/group/JavelinCode/files/Javelin%20Stamp%20IDE/lib/stamp/core/
  
  Then get my Format class (Format.java) here:
  
  http://groups.yahoo.com/group/JavelinCode/files/Javelin%20Stamp%20IDE/lib/stamp/util/text/
  
  There is also a pdf file for the Format class.
  
  Complete Format application package with demo programs (Appnote 012):
  
  http://www.parallax.com/javelin/applications.asp
  
  char[noparse]/noparse line = new char[noparse][[/noparse]7]; //allows up to 6 chars (decimal 16bit number with sign)
  
  int[noparse]/noparse i = new int[noparse][[/noparse]1]; //placeholder for binary int
  
  Terminal.getString(line,6); //read up to 6 chars from terminal
  
  Format.bscanf(line,0," %d",i); //read int value skipping any leading whitespace
  
  Now i[noparse][[/noparse]0] is the binary value you entered via Terminal.
  
  Read the pdf file for more·info on bscanf.

  Thanks alot.
  
  I was started writing my own last night thinking that is what·I had to do.· I wondered why though that the Basic Stamp debug window had all of this in there and not the javelin.

  The basic stamp is an other microcontroller and exists longer than the javelin.
  
  Look around the files section on yahoo group JavelinCode.
  
  http://groups.yahoo.com/group/JavelinCode/files/
  
  Most code I have put there are general utilities, because the Javelin
  
  lacked those. The Format class is very useful for user interface code
  
  using the IDE message window, or for printing to char arrays.

  I am getting an error with the Format command
  
  ·Format.bscanf(line,0," %d",value);·· <--- says either misplaced or not found????· and the Format.java file is in the

  The Format.java must be placed into
  
  %javelin_ide_path%\stamp\util\text folder.
  
  If that folder does not exist, create it first.
  
  In your main class
  
  import stamp.util.text.*;
  
  then you can use
  
  Format.printf("just some text\n"); //same as System.out("just some text\n");
  
  Format.printf("a hex value %04x",value); //print hex number with leading 0's to message window
  
  Format.bscanf(line,0," %d",i); //read a binary int
  
  etc.

  That took care of it.· I did not have the text folder, went to parallax and redownloaded the whole app zip file.
  
  I also had to look more closely at the bscanf parameters I was not accepting an int [noparse]/noparse back in.· I appreciate all of your help.

  bscanf() is very handy for multiple parameters on a single line.
  
  For example, if you input values for x, y and z via terminal, you
  
  just enter the values seperated by spaces, on a single line.
  
  In your code
  
  char[noparse]/noparse line = new char[noparse][[/noparse]81];
  
  int[noparse]/noparse x = new int[noparse][[/noparse]1];
  
  int[noparse]/noparse y = new int[noparse][[/noparse]1];
  
  int[noparse]/noparse z = new int[noparse][[/noparse]1];
  
  int k; //parser index
  
  Terminal.getString(line,80); //single line holding multiple values
  
  k = Format.bscanf(line,0," %d",x); //parse x
  
  k = Format.bscanf(line,k," %d",y); //parse y
  
  k = Format.bscanf(line,k," %d",z); //parse z
  
  In the same way you can use bprintf() to assemble a string into a char array
  
  without the overhead of String methods (the Format class does not use Strings,
  
  although it accepts Strings in formal parameters)
