abs1If c-a and a-b are the same sign, that means that c and b are on opposite sides of a on the number line, and hence, a is between c and b. If you divide two numbers of the same sign, you get a positive number, if you divide numbers of different signs, you get a negative number. You can check only the sign of a number by dividing the number by the absolute value of itself. Hence, when the final result is 1, the differences are the same sign, and a is between c and b.Whether to make a numerical comparison, or alphabetical order comparisonCatch errors. Runs the first script. If it succeeds, nothing else happens. But if it has an error (something that would otherwise result in a red halo around the block), then the second script is run, with the text of the error message that would have been shown in the variable ERROR.

pt:tenta executar _ e, em caso de erro _ , executa _ returnThrow an error. Makes a red halo appear around the script that runs it, with the input text shown in a speech balloon next to the script, just like any Snap! error. This is useful to put in the second script of SAFELY TRY after some other instructions to undo the partial work of the first script.

pt:lança o erro _ LET (FOO) BE (5) is equivalent to SCRIPT VARIABLES (FOO) SET (FOO) TO (5)

pt:cria a variável de guião _ com valor _ Catch errors in a reporter. Evaluates its first input. If that expression successfully reports a value, this block reports that value. If the expression causes a Snap! error, then the final input slot is evaluated with the text of what would have been the error message in variable ERROR. SAFELY TRY then reports the value of that final expression. Sometimes you'll want to throw an error in the final expression. You can put an ERROR block inside a CALL block to do that.
