As explained in the 4D documentation, the EXECUTE command enables you to execute “a 4D expression.” However, the following two limitations are very important: this expression must be contained in one line and the EXECUTE cannot execute a test containing keywords such as If, For, etc.

In other words, if a piece of code contains tests that need to be executed, they cannot be directly run by the EXECUTE command .

This technical note offers a set of seven methods that parse, analyze, and execute a 4D method containing tests and keywords that may be contained in a source.
