Summary
A Turing machine is specified by a list of conditional actions (if state A input B, ...). Natural language descriptions tend to use qualifiers instead of conditions. (cbb 6/96)
Subtopic: status register
Quote: natural language emphasizes the action while programming languages emphasize the conditions and control structures [»millLA10_1978]
Subtopic: conditional control by clocks
Quote: PL.8 intermediate language uses a status register for compares and conditional jumps; no source language control structures [»auslM6_1982] Quote: condition codes difficult to optimize; use values instead and generate condition codes at final assembly; uses peephole optimization [»auslM6_1982]
Subtopic: nesting conditionals
Quote: flow operators deactivated if an operand clock is false [»benvA1_2003] Quote: Lustre controls program activation by clocks Quote: if activation condition is false, a flow node's value is either frozen or a default value; deactivation by clocks too restrictive [»benvA1_2003]
Subtopic: Babbage's analytical engine
Quote: with Pancode, conditional evaluation of predicates can be done without side-effects or sentinels [»jonsD8_1987] Quote: found a nestable conditional construct was easier for novices than a branching conditional construct [»simeME1_1973]
Subtopic: conditional goto
Quote: Babbage's analytical engine can backup and advance the operation cards to any extent; can make judgments based on any number of conditions [»babbC_1864, OK]
Subtopic: problems with conditional
Quote: equations may be numbered; the interpreter included a goto and conditional goto instruction [»laniJH1_1954]
Quote: in paper solutions, 90% of occurrences of 'then' concerned sequencing; instead of consequence [»paneJF2_2001] Note: a programming language should minimize conditional code; e.g., Turing machines are all conditional
