Well, perhaps I do - it's just that I've never tried this:</div> <div><br></div> <div>I was recently told by the vendor that if you have your main program in a script not encapsulated in a method, then a lot of the "syntactic sugar" one would expect is not available to you. I suspect embedded default parameters might be included in this.</div> <div><br></div> <div>For this reason (and others) I am contemplating forcing the script writer to encapsulate their main program code in a "main" subroutine, which I would then call. Of course, this would mean that all V1 scripts would need tweaking, but then that's probably the case anyway.</div> <div><br></div> <div>Try putting your main program in a sub(routine) and calling it:</div> <div><br></div> <div> sub main()</div> <div> ...</div> <div> program statements</div> <div> ...</div> <div> end sub</div> <div><br></div> <div> main() // Call main</div> <div><br></div> <div>and see if that resolves the issue.
