LEN

d = LEN(x)

Returns the length of the variable x.

The return value d depends on the type of the variable x:

Type	Return Value
number	length of the STR(x)
string	length of the string
array	number of the elements
map	number of the elements

Example

i = 10
f = 1.234
s = "abc"
dim a1(9)           ' Array with 10 elements
dim a2(9,9)         ' Array with 10x10 elements
m = {x:1, y:2, z:3} ' Map variable with 3 elements

print len(i)        ' Output: 2
print len(f)        ' Output: 5
print len(s)        ' Output: 3
print len(a1)       ' Output: 10
print len(a2)       ' Output: 100
print len(m)        ' Output: 3
