The pseudocode in Fig. shows the use of lip for OOC index arrays and in-core index arrays. Thanks to the introduction of the concept of in-core section, the Inspector/Executor approach remains almost unaltered. The whole index array is stored in a file and only a small part of it - i-section - is loaded into main memory to enable the previously described optimization. This is illustrated in Fig. . This step is repeated for all i-sections. In this way, the technique successfully used for irregular in-core problems has been generalized for irregular OOC problems with in-core data arrays and OOC index arrays.
