Progress Interview Questions and Answers

1
What are the sections involved in Progress procedure programming?

There are four different sections involved with the procedure programming and it is as follows:

  • Progress procedures are also uses widgets that define the first part of the application and it allows easy use of procedures.
  • It consists of three DEFINE VARIABLE statements for the following variables:
  • Text data: that are collection of characters and then
  • String: that is used to initialize the text data and uses it in the format given by the language.
  • Creation of user interface is the second part that allows the DISPLAY statement to create the interface and display it on the screen.
  • Enabling of the widgets used in the Progress procedure and it allows the ENABLE statement to enable the functionality of the widgets.
  • Execution of the Progress procedure block consists of the text data and presents the complete interface for the users to interact with the application.

Explain what is the use of ASSIGN statement in progress database?

You also have encountered the ASSIGN statement. ASSIGN moves data from the screen buffer
to the record buffer,

Once you move changes from the screen buffer to the record buffer, or make changes directly

to the record buffer, Progress understands that you want those changes written to the database.

Progress does not immediately write the changes to the database. When the write occurs is based

on other factors. The next section describes how Progress handles database writes.

This is the syntax for the ASSIGN statement

  • The edit buffers are used as a temporary storage area in the computer memory that is used by the procedure.
  • It creates and edits the procedure used by the Progress and the editing is saved in the save buffer in procedure files.
  • Procedure file is just a simple text file that consists of one or more Progress procedures by default and having default conventions for use.
  • The files can be edited by using the Procedure editor that provides menu commands and allow the editing and management of the multiple edit buffers.
