Template:Str sub long

Instructions for {{Str sub long}}

{{str sub long|text|start|length}} = Substring of text starting at start and containing length characters. Base 0: the first character is numbered 0, and so on, e.g. {{str sub long|20090624130510|8|2}} returns the 2 characters starting at the 9th, i.e. "Template:Str index/logicTemplate:Str index/logic"

start + length must be less than 100. Only operates on a limited character set.
