9.224 START_FUNCTION_EDIT
Þ Note: Built-In Function Rules.
Starts an "edit session" on the definition of a nominated LANSA function definition.
The edit session can be used to define a new function or alter an existing one.
A function edit session must be started and ended within a process edit session on the parent (i.e.: owning) process. Multiple edit sessions on functions within the same process may be conducted serially (but not concurrently) within the same process edit session.
For example:
START_PROCESS_EDIT
START_FUNCTION_EDIT
<< work with function A >>
END_FUNCTION_EDIT
END_PROCESS_EDIT
or:
START_PROCESS_EDIT
START_FUNCTION_EDIT
<< work with function A >>
END_FUNCTION_EDIT
START_FUNCTION_EDIT
<< work with function B >>
END_FUNCTION_EDIT
END_PROCESS_EDIT
The function definition is locked for exclusive use throughout the function edit session.
Only one function definition can be edited at one time (ie: it is not possible to concurrently edit two or more function definitions within the same job).
A function edit session should be terminated by using the END_FUNCTION_EDIT Built-In Function to ensure all locks/etc are released/shutdown in an orderly manner.
Any function edit session that receives a fatal error will have an END_FUNCTION_EDIT and an END_PROCESS_EDIT operation automatically issued.
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.
