Many moons ago I tried to count the number of all possible dataset names. Assuming "correct names", that means up to 44 characters, no digit on first char in the qualifier, 1-8 char per qualifier, etc. I gave up - too complex. Especially because of number of quals vs qual. length relationship. Last, but not least: it makes no sense. ;-) -- Radoslaw Skorupka Lodz, Poland W dniu 23.03.2023 o 15:34, John McKown pisze: > I got curious about how many possible different values could exist in a > dataset "node".
