A method is provided for retrieving data stored in a data source at pages having a predetermining size. A computing system receives a page request for requesting a new page, within data that are selected in the data source according to a query and are then to be filtered according to one or more filtering criteria external to the data source. A pagination structure (comprising an end point in the selected data of a last previously requested page that has been previously requested) is associated with the page request; the pagination structure is used to retrieve the data following the end point of the last previously requested page and to filter them into the new page. A computer program product for performing the method and a corresponding system are also provided.

Pagination of data filtered after retrieval thereof from a data source

A method () of editing program code is proposed. The program code consists of main instructions written in a high-level language. Typically, the program code further includes one or more sets of service instructions, which are not directly connected to a desired algorithm (such as tracing instructions for debugging purposes, performance measuring instructions, and the like). In the solution of the invention, each set of service instructions is enclosed (-) between a pair of predefined comments defining a starting tag and an ending tag. An editor of the program code is provided with commands for automatically disabling () the service instructions (converting them into corresponding comments); at the same time, the disabled instructions are condensed () on the monitor. Additional commands are available for automatically enabling () and restoring () the service instructions.
