"How long is a piece of string?" Is one of many well known sayings. In this
article you will find out how to do that, and lots of other things.
String Conversion Functions
These four functions manipulate the ANSI codes and translate them into characters, or
vice versa.
Asc() Chr$() Str$() Val()
Ansi String Conversion
Using the Asc() function, it will return the ANSI code for the first letter in
the string, e.g.
R=Asc("ABCD")
Will return 65, which is the ANSI code for the letter "A".
Character Conversion
Using the Chr$() function, it will return the letter for the ANSI code given,
e.g.
R$ = Chr$(65)
Will return the letter "A", which is the 65th character in the
ANSI table. The value of the ANSI code must be between 0 and 255.
String Conversion
Using the Str$() function, it will convert the value to a string, e.g.
X = 4.1 S$ = Str$(X) MsgBox S$
The message box will appear with 4.1 in it.
Value of string
Using the Val() function, it will return the value of the string up to the first
non-numeric character, e.g.
R$ = "3.123E12" X = Val(R$)
X will be 3.123000 It converts all the characters after the first non-numeric to 0. In
this case, 3 characters were converted to 0.
String Concatenation
This simply means the joining of strings. Pretty simple yet very effective. E.g.
Fname = InputBox("Enter First Name")
Lname = InputBox("Enter Last Name")
YourName = Fname & " " & Lname
Print "Hello " & YourName
