Library Compare Utility |

The Library Compare utility allows you to compare panels from the same library or from two different libraries.

To invoke this utility, use one of the following methods:

Location | Method
From the PxPlus IDE Main Launcher | Expand the Graphical Application Builder (NOMADS) category. Then expand the Utilities category and select Compare.
From NOMADS Library Object Selection | Select the Compare tool bar button or select Utilities > Compare from the menu bar.
From the NOMADS Session Manager | Select Library > Compare from the menu bar.

The following window is displayed:

This window consists of the following:

File Name | Displays the selected library name for comparison. Click the drop-down arrow for a list (up to nine) of previous selections. Click the Query button to specify a file name.
Panels | Displays a lookup list (name and expanded description) of the available panels in the selected library. You can highlight and select panels individually for comparison.
Show Identical Panels | Check box to indicate that a confirmation message is to be issued when compared panels are identical.
Case Sensitive | Check box to indicate that the compare should detect differences in text casing. Default behavior is a case insensitive compare. (The Case Sensitive check box was added in PxPlus 2020.)
Suppress | Provides selections for excluding or not excluding control position coordinates and/or tab stops from the comparison. Available selections are Nothing, Position, Tab Stop, Both Position & Tab Stop. (Default is Nothing.) (The Suppress drop box was added in PxPlus 2018.)
Compare |
Single | Button used to compare a single selected panel in the Old Library with one selected from the New Library.
Corresponding | Button used to compare only panels with the same name when comparing two libraries.
All | Button used to compare all panels with the same name in the two libraries and identify panels that are unique to only one of the libraries.
Close | Exits the Library Compare utility.

Once panels have been compared, NOMADS displays a Compare List on the screen. It shows any differences and unique elements found in the comparison. This report can be printed to hard copy, if required.
