SQS to SQF conversion

SQF Syntax has been introduced in Operation Flashpoint: Resistance v1.85 and is the Arma series' main scripting language since. The main differences with SQS Syntax are:

• execVM is used (instead of exec for SQS)
• Every command has to end with a semicolon (;)
• the following commands disappeared:
  • goto/#label (Note, # is a command in itself in Arma 3)
  • exit - a partial SQF equivalent can be found in exitWith
• Line returns do not impact code
• SQF can return a variable, where SQS cannot

Conversion examples

SQS	SQF
Comment
; This is a comment ; This is a ; multiline ; comment comment "this is a comment"; "this is a comment";	// This is single-line comment /* This is a multiline comment */ comment "this is a comment"; "this is a comment";
Condition wait
@CONDITION @ not alive player	waitUntil { CONDITION }; waitUntil { not alive player };
Delay
~DELAY ~5	sleep DELAY; sleep 5;
Conditional command
? CONDITION : COMMAND ? alive player : player setDammage 1	if (CONDITION) then { COMMAND }; if (alive player) then { player setDammage 1 };
Multi-conditional command
? CONDITION : goto "SKIP" COMMAND_2 goto "END" #SKIP COMMAND_1 #END	if (CONDITION) then { COMMAND_1 } else { COMMAND_2 };
Cycle
#loop COMMAND ~DELAY ? CONDITION : goto "LOOP"	while { CONDITION } do { COMMAND; sleep DELAY; };
Cycle with step
_i = 0 #LOOP COMMAND _i = _i + 1; ? _i < COUNT : goto "LOOP"	for "_i" from 0 to COUNT -1 do { COMMAND; };
Structured conditional command
? VARIABLE == VALUE_1: goto "SKIP_1" ? VARIABLE == VALUE_2: goto "SKIP_2" DEFAULT_COMMAND goto "END" #SKIP_1 COMMAND_1 goto "END" #SKIP_2 COMMAND_2 #END	switch (VARIABLE) do { case VALUE_1: { COMMAND_1 }; case VALUE_2: { COMMAND_2 }; default { DEFAULT_COMMAND }; };
Exiting
? CONDITION : COMMAND_2 ? CONDITION : exit COMMAND_1	if (CONDITION) exitWith { COMMAND_2; }; COMMAND_1;
