The following can be used to manipulate and retrieve string details from variables.

These should be written in the following format: varname.method(arguments), e.g. myVar.subStr(3,2) if your variable name was "myVar" and you wanted to use the subStr function to find the 2 characters that begin 3 from the left.

Using the table below, you could for example find out the 4th letter of the variable named var that has stored the word "hello" like so:

// Don't forget almost all internal "counting" starts at 0, not at 1...
// so the 5th character would actually be 0, 1, 2, 3, '''4''' <--- 4! 
var="hello"
echo "The 5th letter in the word hello is: " + var.charAt(4)

Result:
01:25:34 The 5th letter in the word hello is: o
01:25:35 Script stopped

Methods

Method	Type	Description
charAt	String	Returns the character in the position specified by the index parameter.
charCodeAt	Number	Returns the numeric Unicode character code of the character at the specified index.
concat	String	Appends the supplied arguments to the end of the String object, converting them to strings if necessary, and returns the resulting string.
fromCharCode	String	Returns a string comprising the characters represented by the Unicode character codes in the parameters.
indexOf	int	Searches the string and returns the position of the first occurrence of val found at or after startIndex within the calling string.
lastIndexOf	int	Searches the string from right to left and returns the index of the last occurrence of val found before startIndex.
localeCompare	int	Compares the sort order of two or more strings and returns the result of the comparison as an integer.
match	Array	Matches the specifed pattern against the string.
replace	String	Matches the specifed pattern against the string and returns a new string in which the first match of pattern is replaced with the content specified by repl.
search	int	Searches for the specifed pattern and returns the index of the first matching substring.
slice	String	Returns a string that includes the startIndex character and all characters up to, but not including, the endIndex character.
split	Array	Splits a String object into an array of substrings by dividing it wherever the specified delimiter parameter occurs.
substr	String	Returns a substring consisting of the characters that start at the specified startIndex and with a length specified by len.
substring	String	Returns a string consisting of the character specified by startIndex and all characters up to endIndex - 1.
toLocaleLowerCase	String	Returns a copy of this string, with all uppercase characters converted to lowercase.
toLocaleUpperCase	String	Returns a copy of this string, with all lowercase characters converted to uppercase.
toLowerCase	String	Returns a copy of this string, with all uppercase characters converted to lowercase.
toUpperCase	String	Returns a copy of this string, with all lowercase characters converted to uppercase.
valueOf	String	Returns the primitive value of a String instance.

charAt

Usage: charAt(#)

Returns the character in the position specified by the index parameter.
