Post/Get variable availability

[gwilburn]

I am trying to retrieve the variables (parameters) passed to an RPG button program using vvIn_Char(). But I'm attempting to do this in a form helper program.
It appears these variables are only available within the button program??

Do I need to use app variables instead?

Thx

Are you trying to reference a "form helper" program in the "Call RPG Program" action? If so, this cannot be done.

The form helper program is called later...
1. Button program is called with several variables passed into it
2. Form Helper program may or may not be called afterward

I would like to get the the variables (passed into the button program) if/when the form helper is called

Sounds like I need to store the values in app variables when the button program runs?

Sorry, I am still not completely understanding the process flow. But generally I would say yes, if you want to share values across different programs you would either want to use app variables or use session variables via vvUtility_setSessVar / vvUtility_getSessVar.

I have it working with app variables.

The situation:

A button click prompts the user for two values, then creates a new RMA Order (return) with header and detail lines. These two values are used to populate values in the database records created by the button click - works great.
The app has an "add" button allowing the user to add a new line item to the RMA Order by way of a form.
I would like to populate the form with those two values previously entered by the user.

Populating the app variables in the button RPG program is working - I just didn't know if there was another (better) way.
