parameters & nested ifs

Former Member — Fri, 10 Jun 2005 22:14:50 GMT

Hi,

I have a problem with nested if conditions. I have to take in a field A as a parameter which has two values say 10 and 11 and value the should be selected depends on another field value say B which again has two values 1 and 2 and say this is how 10 and 11 are related to each other:

if A=10 & B=1 then write 10 else if A=11 and B-2 write 11.

the user can enter either 10 or 11 in the selection screen.

so right now the if condition that I have which is not working is as follows:

If A = 10.

If B = 1.

A = 10.

elseif B = 2.

A = 11.

else

A = 11.

endif.

WHat is happening is that it only writes out correct value for the first condition when a =10 but writes nothing when a = 11. So can somebody correct the condition and tell me what to do?

Thanks,

Try this as a fix for your solution

if A = 10.

If B = 1.

A = 10.

elseif B = 2.

A = 11.

endif.

A = 11.

endif.

if A = 10 and B = 1.

A = 10.

elseif A = 11 and B = 2.

A = 11.

endif.

This is a nutty one for a Saturday morning.

If this is exactly your requirement: <i>if A=10 & B=1 then write 10 else if A=11 and B-2 write 11</i> .

Then only Rishi's second attempt gets this result:


if A = 10 and B = 1.
  A = 10.
elseif A = 11 and B = 2.
  A = 11.
endif.

If you want to achieve this using nested ifs then you can do it:


if A = 10.
  if B = 1.
    A = 10.
  endif.
elseif A = 11.
  if B = 2.
    A = 11.
  endif.
endif.

But, setting A = 10, or A = 11 is meaningless in this context as if A = 10 then it will always be 10, regardless of the value of B, and the same if it is 11, it will always be 11.

So, better to set a third variable C, like this:


if A = 10 and B = 1.
  C = 10.
elseif A = 11 and B = 2.
  C = 11.
endif.
WRITE: / C.

I hope that makes sense.
