NCL does not reserve any words for its own use in an NCL procedure except the
Boolean operators AND, OR, XOR, and NOT. Apart from the Boolean operators, NCL
regards a keyword as a reserved word only in the context of a particular core
statement or verb. It has special meaning only within the current statement.
Interpretation of Alphabetic Characters
NCL is generally case-insensitive. NCL converts alphabetic characters to uppercase
only when the characters are significant in the current context. When alphabetic
characters are not significant in the current content, NCL ignores their case. Keywords
are significant in the current context. As a result, you can use either uppercase or
lowercase letters for NCL keywords.
