If you keep your Standard scripts, you can always upload them directly into webProg3, modify them, and re-save. It is recommended that you save yet another Standard script at least. But you can also save another "friendly" version if you need to.
However, what can you do if you lose a Standard script, but still have the Friendly version?
1. If the Friendly version is for MOBILE, then there is nothing you can do. Mobile-Friendly scripts cannot be loaded into webProg3, or
"defriendified" into Standard form. Your only option is to re-create them again from scratch.
The other types of friendly scripts CAN be defriendified, provided they have been created correctly (see instructions for this).
2. If you are using the old version of webProg3 (build 3.391), use the Defriendify Utility HERE to convert your script(s) back to Standard form. It/They can then be uploaded into webProg3 for modification.
3. If you are using the 2025 version of webProg3 (build 3.421), then you can upload your (non-mobile) friendly script(s) into it without
further ado. [See item 19 of this HELP - "WebProg3 2025" - for a description of the upload process.]
