From e7a99de4f711302d57fe22682a9a8c3cfddb458c Mon Sep 17 00:00:00 2001 From: Ryan Harrison Date: Fri, 28 Jul 2017 14:07:04 -0400 Subject: Convert calls to Mid() to Left() or Right() if possible The various string/byte classes support Mid(), Left(), and Right() for extracting substrings. Mid() can handle all possible cases, but Left() and Right() are useful for common cases and more explicit about what is going on. Calls like Mid(offset, length - offset) can be converted to Right(length - offset). Calls like Mid(0, length) can be converted to Left(length). If the substring being extracted does not extend all the way to one of the edges of the string, then Mid() still needs to be used.
