## Remove/Insert

This function will remove a counted number of characters at a specified index from the beginning or end of a field or named variable. It will optionally then insert a string at a specified index from the beginning or end of the modified item. If you do not wish to remove characters before inserting, set the number of remove characters to 0. If you do not wish to insert anything, leave the then insert field blank. Please note that the indicies start from 0 not 1. When from the end is specified, the last character is at index 0, the next to last character is at index 1, etc. When inserting from the beginning, characters get inserted at the specified index. When inserting from the end, characters get inserted after the specified index.
