if else

  Hi All

        I want to calculate amounts for a large number of codes eg:

        if code in ('BBB','PPP') then amount = 1;

                but I want it to exclude the codes PPPBB and PPPCC as that code will be calculated separately eg:

        if code in ('PPPBB','PPPCC') then amount = 2;

Sorry can't get my head around this.

Thank you

Re: if else

Hi Amir

The 1st in statement will select all codes that have PPP in them including PPPBB which I do not want.

Re: if else

Hi,

Looking at the data set produced, I see the following:

Obs    code     amount

1     PPPBB       2

2     PPP         1

3     PPPCC       2

4     BBB         1

Did you want something different? If yes, then please give sample input data and the output data you want to see.

Regards,

Amir.

Re: if else

Hi,

No problem. As you might have realised, the in operator, as used in the code, will check if the variable is equal to any one of the values in the parentheses, not contained in one of the values.

Hope that's clear.

Regards,

Amir.
