Can we check a program from a program.

[webmasterpdx]

I'm writing a custom program editor and want to be able to check the code like the regular editor can. Since the function is already there to provide the functionality for the CHECK button in the existing editor, I'm wondering if there is a way for a program to access that function, to either take a program or the contents as a string and check it and return the location of the error if there is one (like the existing editor does).
Thanks
