Search operation of string

Hi Experts,

I have 2 variables (both are characters so search operations are possible)

1) 10,000.000

2) 10,0000.

I need to check if the a variable has both ', 'and '.'

Means the first varibale must return me true and the second one false

Let me know if there is solution , without Searching first with , and again Searching with .
