9.104 GET_FIELD_INFO
Þ Note: Built-In Function Rules.
Retrieves a list of field related information from the LANSA internal database and returns it to the calling RDML function in variable length working lists.
Special Note: This Built-In Function provides access to very advanced facilities that basically allow RDML functions to construct new RDML functions.
This is a very specialized area that requires very good knowledge of the LANSA product. Use of this Built-In Function in a "commercial" application (e.g. Order Entry) is not normal and should not be attempted.
Þ This is a Specialized Built-In Function for use in a Development Environment only.
