RE: RPG Indicators

Is it possible to control the affect of DSPATR through the program rather
than using indicators on the DSPATR key word?  

A               FIELDX  10A             
        88                              DSPATR(ND)
        89                              DSPATR(PC)     

E.g. - Here DSPATR(ND) and DSPATR(PC) will be affected only when 88 and 89
is on. Can this be simulated by using Program to System variable on DSPATR
as described below. I have never used this method in coding. Seems to be a
good approach, providing it gives me the flexibility to manipulate different
attributes simultaneously.

Also, what are the Hex values for position cursor, no display etc. .. etc..
(barring the color codes)

Hi Fong Lon,

the use of 99 indicators is not modern, we should avoid indicators at all,
but this would not help you quick, even it is true (=for the next time).

Instead of an indicator you could also do:

pass your attribute to the DSPF as variable: 
*note: extracted from an article by Christian Rehn, www.common.at/info.html

DDS:
A               FIELDX  10A             DSPATR(&ATTR)
A               ATTR            1A      P       


CLP:
        CHGVAR   &ATTR   X'21' 
        SNDRCVF

other Programming language: 
C       MOVE  X'21'     ATTR     1      (alpha) 
C       EXFMT dsprecordformatname

(the hex attributes you need for DSPATR should be in your DDS manual)

I add to Christians sample: don't forget that in this case you/your program
is responsible for ATTR (=you have to fill it always with a valid hex value
or you recieve a hard I/O-Error).

The answer of Jon Erickson, that someone uses a 99-element array (by MOVEA
*IN) is also in my opinion a hazard to be managed and maintained. It also
doubles the problem, that "N47" or "78" does not mean anything to the next
programmer.
:-(   or ask Toronto for coloured indicator arrays....  


Hope it helps
