Doubt about Progress 4GL

Question

I’m new to Progress development, and I’m having a hard time understanding what this piece of code does:

define variable cRunFile as character no-undo initial "gpldnfbr.p".

        {us/gp/gpmnp02.i cRunFile 10 """(input p_oid_lgdd_det,
                                         output p_exclude_app)"""}

I asked for a little help here and my supervisor told me that it’s a hook that calls another program, but I still wondered, it wasn’t very clear, you know.

Answer 1

I work with Progress 4gl for about 9 years, rs... I will try to explain what I understand...

• define variable - Standard definition of variable
• cRunFile - Variable Name
• as character - Type of Variable
• no-undo - No need to store for possible shredding

• initial "gpldnfbr.p" - Initial value of the variable

• {us/gp/gpmnp02.i - Include file as if the contents were inside the program, just a way to make the code cleaner

• cRunFile - Calling the "gpldnfbr.p" declared in the variable
• 10 - I believe it is the value of a parameter
• """(input p_oid_lgdd_det, - Input parameter
• output p_exclude_app)"""} - Output parameter

I hope I contributed :)
