Re: Subfile indicator question...

Hi Patrik,

Yes - true - you don't need N50 COLOR(GRN) - but you have to be careful, that the unconditional attributes and the conditional color doesn't "overlap" badly.

And - well - in fact there is a very rare case, where 5250 needs 2 attribute bytes (aka empty spaces) before a field. And that's the case if you use CNTFLD for multi-line-fields. In this case you have to leave 2 spaces between the field/constant and the CNTFLD-field.

Regards,
Daniel

Assuming you've done things correctly...

How much space have you left between fields? You need at least 2 ( maybe 3? it's been a while) spaces between fields.

Wrong. The attribute byte is just a the start (and end) of a given "region" on screen and needs exactly one position each. It doesn't matter if we're talking subfiles or plain screens. There is no designated end but in fact the start of another "region" with different attributes.

This is the main reason many DSPF elements go into in position 2 of a screen line, and not 1: You have a nice adjustment, and space before the element for attributes.

The screen buffer is circular. You can place your screen elements in position 1. The attribute position then wraps back into into the last position of the line before. It boils down on whether this position is prone to being overwritten to exploit this possibility successfully.

This is from my experience, in part being reinforced by statements in the DDS Reference, and Application Display Programming books.

:wq! PoC
