---------------------------------------
+*charat(<string>,<index>)
+
+ Returns char at specified index. If index is out of range,
+ returns empty string.
+
+ Example:
+
+ charat("This is a string", 10); //returns "s"
+
+---------------------------------------
+
+*setchar(<string>,<char>,<index>)
+
+ Returns the original string with the char at the specified
+ index set to the specified char. If index out of range, the
+ original string will be returned.
+ Only the 1st char in the <char> parameter will be used.
+
+ Example:
+
+ setchar("Cat", "B", 0); //returns "Bat"
+
+---------------------------------------
+
+*insertchar(<string>,<char>,<index>)
+
+ Returns the original string with the specified char inserted
+ at the specified index. If index is out of range, the char
+ will be inserted on the end of the string that it is closest.
+ Only the 1st char in the <char> parameter will be used.
+
+ Example:
+
+ setchar("laughter", "s", 0); //returns "slaughter"
+
+---------------------------------------
+
+*delchar(<string>,<index>)
+
+ Returns the original string with the char at the specified index
+ removed. If index is out of range, original string will be returned.
+
+ Example:
+
+ delchar("Diet", 3); //returns "Die"
+
+---------------------------------------
+
+*strtoupper(<string>)
+*strtolower(<string>)
+
+ Returns the specified string in it's uppercase/lowercase form.
+ All non-alpha characters will be preserved
+
+ Example:
+
+ strtoupper("The duck is blue!!"); //returns "THE DUCK IS BLUE!!"
+
+---------------------------------------
+
+*charisupper(<string>,<index>)
+*charislower(<string>,<index>)
+
+ Returns 1 if character at specified index of specified string is
+ uppercase/lowercase. Otherwise, 0. Characters not of the alphabelt
+ will return 0.
+
+ Example:
+
+ charisupper("eAthena", 1); //returns 1
+
+---------------------------------------
+
+*substr(<string>,<start_index>,<end_index>)
+
+ Returns the sub-string of the specified string inclusively between
+ the set indexes.
+ If indexes are out of range, or the start index is after the end
+ index, an empty string will be returned.
+
+ Example:
+
+ substr("foobar", 3, 5); //returns "bar"
+
+---------------------------------------
+
+*explode(<dest_array>,<string>,<delimiter>)
+
+ Breaks a string up into substrings based on the specified delimiter.
+ Substrings will be stored within the specified string array.
+ Only the 1st char of the delimiter parameter will be used.
+ If an empty string is passed as a delimiter, the string will be placed
+ in the array in it's original form.
+
+ Example:
+
+ explode(.@my_array$, "Explode:Test:1965:red:PIE", ":");
+ //.@my_array$ contents will be...
+ //.@my_array$[0]: "Explode"
+ //.@my_array$[1]: "Test"
+ //.@my_array$[2]: "1965"
+ //.@my_array$[3]: "red"
+ //.@my_array$[4]: "PIE"
+
+
+---------------------------------------
+
+*implode(<string_array>{,<glue>})
+
+ Combines all substrings within the specified string array into a single string.
+ If the glue parameter is specified, it will be inserted inbetween each substring.
+
+ Example:
+ setarray .@my_array$[0], "This", "is", "a", "test";
+ implode(.@my_array$, " "); //returns "This is a test"
+
+---------------------------------------
+
+*sprintf(<format>[,param[,param[,...]]]) [Mirei]
+
+ C style sprintf. The resulting string is returned same as in PHP. All C format
+ specifiers are supported except %n. More info: sprintf @ www.cplusplus.com.
+ The number of params is only limited by eA's script engine.
+
+ See thread: http://www.eathena.ws/board/index.php?showtopic=190410
+
+ Example:
+ .@format$ = 'The %s contains %d monkeys';
+ dispbottom(sprintf(.@format$, "zoo", 5)); //prints "The zoo contains 5 monkeys"
+ dispbottom(sprintf(.@format$, "barrel", 82)); //prints "The barrel contains 82 monkeys"
+
+---------------------------------------
+
+*sscanf(<string>,<format>[,param[,param[,...]]]) [Mirei]
+
+ C style sscanf. All C format specifiers are supported.
+ More info: sscanf @ www.cplusplus.com. The number of params is only limited
+ by eA's script engine.
+
+ See thread: http://www.eathena.ws/board/index.php?showtopic=191157
+
+ Example:
+ sscanf("This is a test: 42 foobar", "This is a test: %d %s", .@num, .@str$);
+ dispbottom(.@num + " " + .@str$); //prints "42 foobar"
+
+---------------------------------------
+
+*strpos(<haystack>,<needle>{,<offset>})
+
+ PHP style strpos. Finds a substring (needle) within a string (haystack).
+ The offset parameter indicates the index of the string to start searching.
+ Returns index of substring on successful search, else -1.
+ Comparison is case sensitive.
+
+ Example:
+ strpos("foobar", "bar", 0); //returns 3
+ strpos("foobarfoo", "foo", 0); //returns 0
+ strpos("foobarfoo", "foo", 1); //returns 6
+
+---------------------------------------
+
+*replacestr(<input>, <search>, <replace>{, <usecase>{, <count>}})
+
+ Replaces all instances of a search string in the input with the specified
+ replacement string. By default is case sensitive unless <usecase> is set
+ to 0. If specified it will only replace as many instances as specified
+ in the count parameter.
+
+ Example:
+ replacestr("testing tester", "test", "dash"); //returns "dashing dasher"
+ replacestr("Donkey", "don", "mon", 0); //returns "monkey"
+ replacestr("test test test test test", "yay", 0, 3); //returns "yay yay yay test test"
+
+---------------------------------------
+
+*countstr(<input>, <search>{, <usecase>})
+
+ Counts all instances of a search string in the input. By default is case
+ sensitive unless <usecase> is set to 0.
+
+ Example:
+ countstr("test test test Test", "test"); //returns 3
+ countstr("cake Cake", "Cake", 0); //returns 2
