LowerCase |

Mid |
Extract substring of first argument:
mid("abcdefg",2,3) -> "cde"
Syntax: mid(str,start,len)
Second argument is starting index, with the first character being at index 0. |
Right |

The string functions can be simply included by using the
jep.setComponent(new StringFunctionSet());
.
This will add the following functions to jep
