RE: **SPAM** Indicator Coding Technique

Here's what I do...(not that I'm a great example to follow LOL)

I define all my DSPF indicators with meaningful names like:

Subfile_End
Subfile_Display
Subfile_Display_Control

For Resetting groups of the indicators I create a "setter" procedure.

P ResetSFLInd       B
D ResetSFLInd       PI
 /free
     Subfile_End = *Off;
     Subfile_Display = *Off;
    // etc....
 /end-free
P ResetSFLInd       E



Thanks,
Tommy Holden

Subject: **SPAM** Indicator Coding Technique

We are developing a set of Free Form RPG coding standards.  (Yes, now.  We
are primarily a COBOL shop just moving over to RPG, stepping boldly into the
1980's!) I want to get the opinion of the group on a technique for setting
DSPF indicators that was proposed.  

 

The proposal was to code a data structure for the screen indicators using
the "N" data type and to use variable names that are meaningful.  The
technique that I am asking for opinions on is that the group of indicators
can be set or tested by using a string such as: '0010000000100000000".

 

I am intentionally not stating my opinion, so as not to affect your
comments.  Thanks for your input.  Code snips follow.  The purpose of this
code it to control which functions keys are available when the screen
displays:

 

D DspFInd         DS                 

D  FunctionKey            1     24   

D  PageDown              25     25N  

D  Request               28     30  

.

.

.

BEGSR $S0Display;                                

   Request  = '100'  ;                            

   FunctionKey = '001000000001000000000000'   ;    

   EXSR $SZGET;                                   

   EXSR $S1DspFmt;                                

 ENDSR;
