Re: A versatile clipboard

I think I mentioned in the other post that numeric values must be strings (with quotes). I was looking into seeing if I could create a DATA statement and instead of doing a SPLIT, I would do a READ directly into the variable name, removing the extra steps in splitting it into an array then looping ...

Re: A versatile clipboard

Another example: a personnel record with mixed variable types. The (simulated) record is put on the cliboard by one program: ' test program for clipboard function ' option base 1 ' *** personnel record, needed by some (query) application *** key$="clint_p" name$="Clinton" surname$="Peacock" birthdat...

A versatile clipboard

Reading about the problem with the clipboard in the "bug reports" section, i came to design and code a versatile clipboard, based on the "dictionary" file type developed not long ago. If the programmer wants to store a collection of data for later use, or use in another program, he packes the data i...

Re: IBM mainframe 360/30 vs. iPad 2019

You are running on an iPad Pro, I believe. That accounts for being able to increase the font size. Your speeds are quite a bit faster than mine and Henk's. I'm not sure how to account for the improved accuracy. Is there better math processing on the Pro? No, i lowered the bias that you added to the...

Re: IBM mainframe 360/30 vs. iPad 2019

I tried both programs and on my iPad Pro 10.5 Inch running iOS 10.3.3, rbytes code just says "Finished" and Henko's code it displays 0.276392. I do not get the matrix rbytes gets. Are you sure that you use the matrix multiply function adapted by rbytes? It must print the matrix! def mat_mul (n,m,ma...

Re: IBM mainframe 360/30 vs. iPad 2019

@ rbytes, I reasoned that If all errors were less than 1.E-13, I would always see a perfect matrix printed, containing only 0s and 1s. That did happen occasionally, but often it didn't. Below are screenshots of three consecutive runs. You might think that accuracy is getting better with each run, bu...

Re: IBM mainframe 360/30 vs. iPad 2019

Thank you for retrieving these memories. I also have bad, but especially good memories of that time of punch cards and other inconveniences. :lol: However, I no longer had any specifications, which is why I was so happy with your comparison with iPad. Very enlightening. Talking about inconveniences...
