I am giving more details about my requirement
I got a file which has two columns, first column is of city and the second is of temperature
I search for the city and get the temperature value and dsplay based on that value
If temperature might be a space or number of space or non numeric or a negative value......I need to display what value
it is and change it to in all the above cases
if it is a positive value ( either decimal) then I need to used it for addition or subtraction
as per your above, it seems you need to give each value seperatly and it is exactly checking for that paticular value,
say suppose
" ") echo got a space;;
its only checking for one space, if i get more spaces its not considering
Please advice
