The OPTIMIZE keyword specifies the level of optimization, if any, of the object.
If *NONE is specified, then the generated code is not optimized. This is the fastest in terms of translation time. It allows you to display and modify variables while in debug mode.
If *BASIC is specified, it performs some optimization on the generated code. This allows user variables to be displayed but not modified while the program is in debug mode.
If *FULL is specified, then the most efficient code is generated. Translation time is the longest. In debug mode, user variables may not be modified but may be displayed, although the presented values may not be the current values.
If the OPTIMIZE keyword is not specified, then the value specified on the command is used.
