OPAC-Global is an innovative tool for the design and development of automated library systems. In this area, efficiency and accuracy are key factors, and this is where Keyran and its macros can be very useful. Creating macros in the program Keyran can greatly simplify and speed up a number of routine operations associated with the management of library systems. For example, you can set up macros to automatically generate reports, update the database, or perform other repetitive tasks. This will reduce the time spent on routine operations and allow you to focus on the more complex and important aspects of your project.
