Set bit in a xString ?

Former Member — Thu, 14 Jun 2012 08:36:07 GMT

Hi,

I would like to store bits in a xstring. Notice that the xstring has a variable length. The length can not be predefined.

To set the bit "1" at position "100" for example, I wrote the following code :

DATA : lw_x TYPE xstring.

set bit 100 of lw_x.

It does not work :after execution, my xstring has a length "0" and the 100th bit is not set.

Could you please advise ?

Regards,

Hi,

DATA lw_x(200) TYPE x.

set bit 100 of lw_x.

Then you can assign that to the XSTRING variable.

Not tested it though.

Please check.

Thanks,

Shambu

Thanks Shambu for your anwer. Your solution works but it does not match my need :

I'd like to avoid to initiate my variables with a "Max fixed size" (I will deal with huge amount of data and I would like my program to be as performant as possible in term of memory comsumption).

In your suggestion, I allocate 200 bits in memory but only the first 100 bits are relevant.
