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 StringsString data types and procedures that create new strings.
Character ConversionsProcedures that convert from character codes to strings and back.
Numeric to String ConversionsProcedures that convert numeric values to strings.
String to Numeric ConversionsProcedures that convert strings to numeric values.
Numeric SerializationsProcedures that convert raw numeric data to and from strings suitable for storage.
Working with SubstringsProcedures that return subsets of strings, or that modify subsets of strings.

Mid (Function)Returns a substring of a string. RightReturns a substring of the rightmost characters in a string. LCaseReturns a copy of a string converted to lowercase alpha characters. UCaseReturns a copy of a string converted to uppercase alpha characters. LTrimRemoves surrounding substrings or characters on the left side of a string. RTrimRemoves surrounding substrings or characters on the right side of a string. TrimRemoves surrounding substrings or characters on the left and right side of a string. InStrReturns the first occurrence of a substring or character within a string. InStrRevReturns the last occurrence of a substring or character within a string.
