Quoting, the p-code optimization technique that eliminates duplicate sections of code, can be controlled with the /Of compiler option. (See “Reducing Duplicate Code with Quoting”.)
Quoting enabled (/Of) is the default. However, quoting makes compiled p-code difficult to read and debug. Therefore, you should use the disable-quoting option (/Of–) during program development. Then you can turn quoting back on (/Of) to produce a smaller, fully optimized release version of your program.
