User-defined Words

User-defined Words

Any word that is defined by the developer is called as a user-defined word and is used to store the data. It can be of maximum length is 30 bytes (except for level-numbers).

Rules -

  • The user-defined word should be unique within the type to which it belongs (that might be a program, paragraph, etc.).
  • User-defined word can be duplicated at the elementary level. The reference should be used with condition-names, data-names, record-names and paragraph-names.
  • Each word atleast have one letter.

Examples -

The below list shows the examples for each type of user-defined name -
