Please keep as a .smcl file. If you can directly produce a PDF by printing to PDF, then you'll be able to simply combine PDF documents later. If you can't print to PDF, you can always copy and paste the smcl text into a word document. It will look messy, unless you format by:
- Changing font type to Courier New
- Changing font size to 8 (that usually makes it fit well)
Hope that helps.
