Message Oracle PLS-00123 - program too large (string)

ERRORprogram too large (string)
CAUSEPL/SQL was designed primarily for robust transaction processing. One consequence of the special-purpose design is that the PL/SQL compiler imposes a limit on block size. The limit depends on the mix of statements in the PL/SQL block. Blocks that exceed the limit cause this error.
ACTIONThe best solution is to modularize the program by defining subprograms, which can be stored in an Oracle database. Another solution is to break the program into two sub-blocks. Have the first block INSERT any data the second block needs into a temporary database table. Then, have the second block SELECT the data from the table.
