This is a very basic thing that you should be able to find via search, but here is goes. This works on standard Account field Rating.

ispickVal(Rating, 'Hot')


text(Rating) == 'Hot'


Please have a look at this example.

Value1= Integer.valueOf('x')
else if(PickList__c == 'Target'){
Value2 = Integer.valueOf('y')

Here what i am doing i habe a custom pick list in which there are two values names as value1 and value2 in which i am storing the integer value of the string x and y.
