I have been fighting mysteries with wrong results or problems in various calcultions using the HP-UX notebook interface. Finally in attempting to make a text file to mail to WRI as a bug I found imbedded "^[" characters in the text file sometimes in the middle of an arguement or in a list . This character doesn't appear in the notebook and I assume its a cell boundary character of some type. However, it sure screws up the calculations. I assume they get there since I develop the notebook commands cell by cell calculating as I go to make sure things work correctly. Sometimes when they don't calculate properly I try another approach in a different cell rather than looking for the character and just assuming the kernel could evaluate the function I asked it to. The only sure way I found to eliminate the character is to cut the entire line or line and retype it. It would be nice that sometime this notebook interface would look for and indicate non-printing characters rather than computing wrong results or complaining about the Tag times in integration limits. In the meantime I use this plain text output file whenever I get mysterious results or messages I feel aren't reasonable. It has help a lot . I also only save bare command files and have been finally getting some real results out of the notebook interface. Best wishes Steve Kramer
