... back to the English Electric Leo. There seems to be a general fear of breaking things. My advice always is exactly Alan's, quick outline of method then advice to 'have a go', see what happens. My schoolmasters used to call it learning by doing. Between the two of you you have clarified the process. I had realised from various postings and help topics that Martin has consistently insisted that Templot never overwrites. That was not my fear, but rather my habit, ingrained over nearly 50 years of trying to economise on memory and disk space. I find it difficult to make myself keep archived versions of anything. I had already explored library templates. My problem not Templot's! I had been deleting older templates in the storage box but now I see that's not necessary. Thank you both for your prompt response.
