case recognitionhelp please!

[mickymoo]

I have written a named entity recogniser. Is there a method to get the program to recognise whether a character ina txt file is uppercase or lower case. I don't care what letter it is, I just want the program to recognise if a letter is Ucase or Lcase. At the moment I am doing a string comparison from a .txt file, bt there must be a better way than this.

Any thoughts gratefully appreciated

Each character has a numeric value associated with it, known as the ASCII value (actually, in recent years it has got bit more complex than this, but we'll go with tradition for now).

Uppercase characters (A-Z) have ASCII values between 65 and 90. And fortunately VB gives us a function to return any given characters ASCII value, so you can write a line something like this:

If Asc(<your_char>) >= 65 and Asc(<your_char>) <= 90 Then
' Character is uppercase
End If
