Left of String (Cross Ref > Commands)

Above returns "abcd" on a string literal. You can, of course, use VarName.Substring(0, 4).

Console.WriteLine("abcdefgh".Substring(0, 4));

Above returns "Mike P".

SubStr(StartIndex, NumberOfCharacters)

Notice JavaScript is 0 based (the first character is character 0).�0 is start character, 6 is number�of characters).�

You can also use substring where both numbers are indexes:

SubString(StartIndex, EndIndex)

The following returns "re".

var sName;
sName = "Mike Prestwood";
sName = sName.substring(6, 8);
document.write(sName); 

var sName;
sName = "Mike Prestwood";
sName = sName.substr(0, 6);
document.write("Hello " + sName);

substr ( const startIndex LongInt [ , const numberOfChars LongInt ] ) String

Alternative syntax:

LeftString = subStr(NameVar, 1, 3)

var
 �LeftString String;

  NameVar String;
endVar

NameVar = "Prestwood"

LeftString = NameVar.subStr(1, 3)

msgInfo("", LeftString)

The above usage of Left and Substring are equivalent.

Left is a traditional VB approach popular with developers moving from VB Classic to VB.Net. Substring is considered the .Net way of doing string manipulation.

Dim FullName

FullName = "Prestwood"
Console.WriteLine("Hello " + Left(FullName, 4))
Console.WriteLine("Hello " + FullName.Substring(0, 4))
