Limits on PL/SQL block?

I'm seeing a "PLS-00123 program too large" error. Oracle's documentation says that the actual limit on the size of the block is dependant on the mix of statements in the PL/SQL block. Does anyone know how Oracle determines this limit? Is it a pure size of PL/SQL block in bytes, or is it number of unique statements in the block, or is it dependant on how much redo that the block may generate?

(I know the recommended solution is to modularize and
break up the statements into multiple blocks, but I'd like to know what are the limits to give us a better idea of determining where to break up the blocks dynamically, so the answer I'm really looking for is what is the limit or how Oracle determines the size limit, and not workarounds, which we're exploring anyway.)

TIA ..Rudy
