If I an given a global, ^G, how can I discover how many subscripts are included?  In other words, how can I determine if the global has 3, 5, 7, ect... or more subscripts?  If I want to $Order through the global I would need to know how many subscripts as I build my code to read the elements, correct?

f  s x1=$o(^G(x1))  d...

f  s x2=$o(^G(x1,x2))  d...

f  s x3=$o(^G(x1,x2,x3)  d...

How can I determine by looking at some type of meta data for a given global, that I have 3, 5, or whatever subscripts?

Please advise,

Thanks...

Thank you very much...

Terminal, thank you...

Greetings,

Can someone please show me via coding example(s) how to write an input prompt that will read in a function key, F7 for example, validate that the key pressed is F7 and then process it all via cache.

Thanks...
