Usage
{{str sub old|text|start|length}}
= Substring of text starting at start and containing length characters. Zero-indexed: the first character is numbered 0, and so on, e.g. {{str sub old|20090624130510|8|2}} returns the 2 characters starting at the 9th, i.e. "13".
Examples
- {{str sub old|1234567|3|2}} —> 45
- {{str sub old| alphabet|0|5}} —> alpha
- {{str sub old| alphabet|5|999}} —> bet
- {{str sub old|alph abet|0|5}} —> alph
- {{str sub old| three words here |4|10}} —> e words h
Any leading spaces are skipped, but internal spaces are counted exactly, yet compressed when displayed.
