AndMZ(a, b)
AndV3(a, b)
a:&b
Description
Logical And with JMP 3 behavior, which treats missing values as 0.
Returns
1 (true) if both a and b are true.
0 (false) if either a or b is false or if both a and b are false.
0 (false) if either a or b is a missing value or if both a and b are missing values.
Arguments

Notes
More than two arguments can be strung together. a:&b returns 1 (true) only if all arguments evaluate to
true. When opening a JMP 3 data table, this function is automatically used for any And function.
