Table of Contents
This chapter describes M language Intrinsic Functions implemented in GT.M. Traditional string processing functions have parallel functions that start with the letter "z". The parallel functions extend the byte-oriented functionality of their counterparts to UTF-8 mode. They are helpful when applications need to process binary data including blobs, binary byte streams, bit-masks, and so on.
Other functions that start with the letter "z" and do not have counterparts implement new functionality and are GT.M additions to the ANSI standard Intrinsic Functions. The M standard specifies standard abbreviations for Intrinsic Functions and rejects any non-standard abbreviations.
M Intrinsic Functions start with a single dollar sign ($) and have one or more arguments enclosed in parentheses () and separated by commas (,). These functions provide expression results by performing actions that are impossible or difficult to perform using M commands.
