Please help me in developing Framemaker Scrips to remove (delete) Soft Returns (Shift+Enter) char's in a paragraph.
No need for a script. The Find/Change dialog can handle this.
If changing to a normal space, and we want to see what's we're doing, it can be entered as \x20 in dialogs.
Now, change-all, for just the current paragraph (if that's what the OP wants), now that might need a script.
For that they can use Change & Find to step through each instance. Most paragraphs aren't long enough for that to take too much time.
