In Oracle SQL, most operations and searches are case-sensitive by default, [6] while in most other DBMSes, SQL searches are case-insensitive by default. [7] Case-insensitive operations are sometimes said to fold case, from the idea of folding the character code table so that upper- and lowercase letters coincide.
If n is greater than the length of the string then most implementations return the whole string (exceptions exist – see code examples). Note that for variable-length encodings such as UTF-8 , UTF-16 or Shift-JIS , it can be necessary to remove string positions at the end, in order to avoid invalid strings.
A system that is non-case-preserving is necessarily also case-insensitive. This applies, for example, to Identifiers (column and table names) in some relational databases (for example DB2, Interbase/Firebird, Oracle and Snowflake [1]), unless the identifier is specified within double quotation marks (in which case the identifier becomes case-sensitive).
Words are used as case-insensitive variables. Like in all dynamically typed languages, variables don't have an associated type, type is associated with values. The result, i.e. the evaluation of a word is returned, when a word is encountered by the do function. The set-word form of a word can be used for assignment.
A block is a grouping of code that is treated collectively. Many block syntaxes can consist of any number of items (statements, expressions or other units of code) – including one or zero. Languages delimit a block in a variety of ways – some via marking text and others by relative formatting such as levels of indentation.

This is a comparison of the features of the type systems and type checking of multiple programming languages.. Brief definitions A nominal type system means that the language decides whether types are compatible and/or equivalent based on explicit declarations and names.
