My thanks to Jamal for his prompt response to my initial question on this topic and also for placing links to regular expression tutorials in the Text Pal help file. I downloaded one of the tutorials; however, it will take many readings and much practice for the concepts to soak in. I have a text document which contains many occurrences of ascii 32 followed by combinations of digits. These combinations vary in number of digits from one to three. I now wish to replace the ascii 32 with crlf pairs followed by whatever group of digits was there prior to the replacement. Stated another way, I want to replace space followed by a group of digits with crlf followed immediately by that same group of digits. I'll make an honest effort to read the docs and not just come here too often with similar questions. Thanks much for feedback.
