Meaning – The term keywordparameter, refers to a parameter that consists of a keyword followed by one or more values. Keyword parameters must be entered after all the positional parameters are entered (if there are any positional parameters to be entered), and then the keyword parameters can be entered in any order.
There are two forms of keywords: regular and self-defining. Their grammar form and their range of possible values are different. Regular keywords have a range of many values, whereas self-defining keywords only have 2 possible values.
Example of usage – “When calling a routine with a keyword parameter, you can abbreviate the keyword to its shortest, unambiguous abbreviation. Keyword parameters can also be specified by the caller with the syntax /KEYWORD, which is equivalent to setting the keyword parameter to 1.”
