Level Effect

0 Code is not optimized. Provided in case other optimization levels cause

errors. Supports symbolic debugging; data is always in memory.

(default)

Code is optimized within statements and across statement boundaries. The

resulting code is more efficient than that produced by lower levels of

optimization. Supports symbolic debugging; data is not always in memory.

2 Code is optimized within statements and across statement boundaries, and

the resulting code is more efficient than code produced by lower levels.

Default: OPTIMIZE 1

Placement: Outside the boundary of a separately compiled program

Scope: The optimization level active at the beginning of a separately compiled

program determines the level of optimization for that program and any

programs it contains.

Dependencies: None

Default: The compiler does not provide additional information if run-time error

148 occurs.

Placement: Anywhere

Scope: Applies to the compilation unit

Dependencies: None
