refrence modifier problem

dipanshu · New User Joined: 16 Jan 2006 Posts: 53 Location: pune

could u please suggest me whether the syntax is correct or not

SUB(X-PACS-SUB)(3:ctra)

where (3:ctra) is a refrence modifier and ctra is a counter variable.

thanks
Dipanshu

dipanshu,

Yes, your syntax is correct. Valuable(subscript)(reference modifier)

Hi,

I dont think we can specify any other thing apart from starting position and length in reference modification.

Syntax is

Var(start pos:length)

Eg: WS_DATE(1:2)

And for subscript you can use this way.

SUB(element)(starting position:length)

Correct me if I am wrong......

Thank you,
Brahma

brahmanandareddy,

Is your concern having a variable as starting-position or length? This can be done. If this is not you're concern, please clairify.

Thanks,

Dave

Hi Dipanshu,

It might be a good idea to tell us what each of the elements are. For e.g.:

SUB is a pic 9(12) variable containing blah-blah..
X-PACS-SUB is a subscript defined as blah-blah...
3 is the 3rd position of ?
ctra is a variable defined as pic 9(2) containing the length of blah-blah...

You might have them reversed and we can't tell unless you give this info.

You can use variable instead of literals in ref/mod. You just have to make sure they contain the values you think they contain.

The reason I requested the info is that I'm suspecious of a data variable named "SUB".
