Explain Ubound function in QTP.

Ubound stands for upper bound. This functions is used to find the upper bound of the array.

Syntax -

ubound(arrayname, dimension)

It returns the upper bound of the arrayname and dimension used is specified in second parameter.
By default dimension is 1.

Example -

Single dimension array

Dim a(2)
'Declare an array with upper bound (index) as 2.

a(0) = 0
a(1) = 0
a(2) = 0

print ubound (a)           'will print 2
print ubound (a,1)        'will print 2

'This will print the value 2 as upper bound of the array is 2.

Please note that size or length of the single dimension array is ubound + 1.

Multi dimension array

Dim b(2,3,5)

print UBound(b, 1)           ' will print 2

print UBound(b, 2)           '  will print 3

print UBound(b, 3)           '  will print 5
