I learned about "mapisdefined" by "???map", which lists all that has

"?mapisdefined" is short help, "??mapisdefined" is extended help.


And you can iterate over just the defined map elements:

? M=Map();
? mapput(~M,12345,1)
? mapput(~M,987654321,Set([1,2,3]))
? foreach(M,e,print(e[1]))
[12345, 1]
[987654321, [1, 2, 3]]
?
