HELP DO Updated A.Sloman, Aug 1988 DO This is a syntax word intended for use with a range of looping constructs, e.g. until <condition> do <actions> enduntil while <condition> do <actions> endwhile for <var> in <list> do <actions> endfor etc. Note: In an early version of POP-11, "DO" was a synonym for "THEN", and as a result there are still some programs using "DO" in conditionals. For upward compatibility this flexibility has been maintained, though opinions differ as to whether the use of "DO" in conditional imperatives should be encouraged. There is also a VED <ENTER>do command described in HELP * VEDCOMMS/ved_do See also HELP *CONTROL - summary of control facilities in Pop-11 *CONDITIONALS - summary of conditional statements, all using THEN *LOOPS - summary of iterative constructs, many using DO *FOR - overview of "for" loops *UNTIL - use of iterative construct UNTIL *WHILE - use of iterative construct WHILE *THEN - use of syntax word THEN in conditionals REF * SYNTAX, REF * POPSYNTAX --- C.all/help/do ------------------------------------------------------ --- Copyright University of Sussex 1988.
