RE: Subfile question

["Bryon Cook" <bryonc@xxxxxxxxxxx>]

I am not a strong programmer but I think I know the answer to this question.
The first two lines:

A     50                                     SFLDSP
A     50                                     SFLDSPCTL

are conditioned so that when indicator 50 is on they will be "executed".

The last line:

 A    N50                                     SFLCLR

will be "executed" when indicator 50 is NOT on (Not50 = N50).  So they are
opposites in that one set of commands is executed when 50 is on and the
other when 50 is off. (I think!)

Subject: Subfile question

I decided I needed some text help on subfiles so I ordered the 
book "Essentials of subfile Programming and advanced topics in RPG IV"

One question I have is a comment the author made:

The SFLCLR must have the opposite indicator value.....

Is he talking about the opposite value of SFLDSP, SFLDSPCTL or both? I 
looked at a sample subfile a friend of mine sent me and he was using 
indicators 51 for the SFLDSP and SFLDSPCTL fields and 50 for SFLCLR....and 
it works...

Can anyone explain what the author might have been talking about?

Here is the example he gave:

A     50                                     SFLDSP
A     50                                     SFLDSPCTL
A    N50                                     SFLCLR

Saying the N50 is the opposite of 50.
