At an HSBC interview I came across the query:

A pic clause is declared as -9(4).999

How many memory locations will this occupy

a)7
b)8
c)9
d)none of the above
and why?

it will occupy 8(eight) bytes.
the reason for that is we have to count "." (dot) aslo.
and comming to "-" it wont occupy any memory unless if we stated "sign traling or leading separate character".[/b]

since it is numeric edited character it will occupy 9 bytes..it will take one byte for '-' sign also.

please advice.

Thanks

Deepa,

The sign will occupy the lower nibble of the right most digit.

Cheers,

Hi Markanthos,
I agree with deepa that the variable is going to take 9 bytes as storage.

An easy way to find out the lenght of any variable is to have a member (say test) in your copylib pds. Then define that variable whose length you want to find out in this member test. Now save this member and open it in fileaid (option F:8 or H:8 as per your installation). If the definition is syntactically correct you will get the lenght.

Let me know if you have any concerns.
David.

even i aslo agree with deepa...i think it will take 9 bytes as it is just a simple declaration...not defined as s9(4).999, in this case it will take i think 8, but when you specify -9(4).999 then it will take 9.

hi, i agree with this it will take 9 bytes, not 8 bytes b'coz it id not declared with s9(4).999.

In this case the sign is called a floating edit char and occupies one byte of storage.

So if I colored the reply in RED, it contains error. GREEN means, it is accepted by the moderator. Any Suggestions?
