问题 For a simulation program I'm working in Delphi 2010. The simulation isn't a problem but I need to use large collection of data which gives a problem.

Is there a way to save my macro changes ? Like an administrator

问题 So I have created a function in my program that allows the user to save whatever he/she draws on the Turtle canvas as a Postscript file with his/her own name.
