The first and second parameters are linked together. The second parameter, interp_type, indicates what type of object the first parameter,to_interpret,is. Here are the possibilities:
SE.FILE indicates a filename, which is read, parsed, and interpreted.
SE.TEXT, which we've already seen above, indicates the source code as a text string.
SE.PRECOMP allows you to execute a precompiled script. You pass as the parameter the script buffer that was given to you by the sePrecompile ScriptEase API call.
