String Functions
Statements and Procedures that work with strings.
Description
These statements and procedures provide many ways to create and manipulate strings and substrings. Numbers can be converted to strings and vice-versa. Procedures are also provided to aid in serialization of numeric data, perhaps for persistent storage.
Creating Strings
String data types and procedures that create new strings.
Character Conversions
Procedures that convert from character codes to strings and back.
Numeric to String Conversions
Procedures that convert numeric values to strings.
String to Numeric Conversions
Procedures that convert strings to numeric values.
Numeric Serializations
Procedures that convert raw numeric data to and from strings suitable for storage.
Working with Substrings
Procedures that return subsets of strings, or that modify subsets of strings.

Creating Strings String Standard data type: 8 bit character string. String (Function) Returns a String of multiple characters. ZString Standard data type: null terminated 8 bit character string.
