Confusion over use of Formula Interpreter

[Williamx]

How do I evaluate a 4-bit input and output an integer value that I am need to map to a different value? Say that I'm evaluating the following inputs (4 in, 1 out):

(((IN(0) AND IN(1)) AND (IN(2) AND IN(3)) = 13) <= We know that 1111b is 15decimal, but I need to translate the value to 13 so that it represents the index of a worksheet that I'll be selecting with the Sequencer.

I am OR'ing each possible combination of the 4 inputs, and each combination needs to output a "special" value that I need to output to represent the index I need.

The result of a logical operation or comparison (OR, AND, =, <>, etc) is 0 (False, zero) or 1 (True, One).

Change the formula to

(IN(0) AND IN(1)  AND IN(2)  AND IN(3) ) * 13

In my limited testing, any non-zero value of the inputs will test TRUE, if any one is zero, then the output is zero, otherwise, the output is 13.

Hello WilliamX,

You can solve this application more flexible and very compact also with Addon Module "VBScript", sale via PREMEGA GmbH -> link under http://www.premega.de/de-02/software_dasylab_vbscript_de.php

Some screen shots for mainpoints from application:




VB Script give you the chance to detect any useful bit combination and put out an value what you needs for this situation.


Best regards,
