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
}}}

||[[#charAt|charAt]] ||String ||var="hello"<<BR>>echo "The 5th letter in the word hello is: " + var.charAt(4) ||Returns the character in the position specified by the index parameter. In this example, returns "o". ||
||charCodeAt ||Number ||var="hello"<<BR>>echo "The char code for the 5th letter in the word hello is: " + var.charAt(4) ||Returns the numeric Unicode character code of the character at the specified index. In this example, returns "111" which is the numeric code for "o"||
||concat ||String ||var="oompa"<<BR>>var2="loompa"<<BR>>var3="dance"<<BR>>echo var.concat(var2," ",var3) ||Appends the supplied arguments to the end of the String object, converting them to strings if necessary, and returns the resulting string. In this example, returns "oompaloompa dance".||
||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 ||mycoords=city.coords.split(",")<<BR>>echo "x:" + mycoords[0] + " y:" + mycoords[1] ||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. ||
