Ok, I had an idea and wanted to get feedback before I go wasting a bunch of time. I have been considering building a routine in LISP - one I've done a long time ago - that will prompt for a selection of files through a dialogue box, then build a script file customized to a specific function. (i.e. DWF files, PLT files, 11x17 plotting, etc.) I thought I'd put the effort into using VBA to make a form interface that the user could simply select the files, then choose buttons (or listbox, whatnot) for the various options that would then be used to construct the SCR file. After which, the SCR would be executed. Which would mean I'd use the Open/Write/Close for external file writing in VBA, wrather than LISP. Here is where I get into a little bit of a snag, as I haven't done this alot. So, here is where I turn to you all for pointers. Also, if someone is willing to share code snippets for the Open/Write/Close, that'd obviously help. Or if there are other ideas or ways that I can control this process strictly through VBA? I thought of that, but wasn't certain where VBA stays loaded and if I would be able to continue to read a file list in order to open/(plot)/close a list of files. Thanks for any advice.
