11. It also may have been the first computer that implemented a single-cycle indirect addressing ability. 12. Logical indirect addressing results in flexible systems that can be changed while the system is in operation. 13. Calculators supporting such programming were Turing-complete if they supported both conditional statements and indirect addressing of memory. 14. The PIC18 extends the FSR / INDF mechanism used in previous PICmicro processors for indirect addressing in two ways. 15. Hence the use of memory indirect addressing was almost the only way of referring to any significant amount of memory. 16. Indirect addressing or field selection was selected if the one-bit field ( i / a ) was set.17. The ENIAC was programmed using subroutines, nested loops, and indirect addressing for both data locations and jump destinations. 18. Unlike Fortran and ALGOL 60, APL ( Address programming language ) supported indirect addressing and addressing of higher ranks. 19. Indirect addressing is a mechanism that appeared in other programming languages much later ( 1963 65 in PL / 1 ).20. The RAM is very similar to the counter machine but with the added capability of'indirect addressing 'of its registers.
