You can compare details of your current database settings with the corresponding settings at a specified earlier time and generate a report listing all differences. The types of change reported include:

• Creation and deletion of elements.

• Changes to the attribute settings of elements.

• Changes in the list order for BRANCH, POGON, DRAWI and BOUND elements.

DIFFERENCE SINCE

Description:

Lets you report all changes to one or more specified database elements since an earlier version of that database. The output is in the form of a report listing all elements and attributes which have changed, with their old and new values. The report can be sent to a file by using the ALPHA FILE or ALPHA LOG commands.

Note:
The database states are compared between SAVEWORK operations. For example, if you last saved your design changes at 9:30 and ask for a comparison since 10:00, the current settings will be compared with those at 9:30.
