Hello VEE-Ites

Does anybody know how to convert a decimal Word into 16-bit binary,
or hexadecimal.

I know it can be displayed in Alphaneumeric Displays in these
formats, but ideally I need to convert to
binary to produce a bit by bit display using Alarm indicators.

Any suggestions will be greatly appreciated

Thank you

Andy,

        I've done this on a regular basis. Don't transform the integer to
     binary which would be a string. Instead, use multiple FORMULA
     objects, each with the formula BIT (A,x) where x is the desired bit
     value to extract. Put all of these into a single User Object with one
     input (the integer value) and several outputs (the bits that you
     desire to monitor) and feed the output pins directly into your
     indicators.
        So if the first 8 bits of you integer have meaning, you have an
     object with one input and 8 outputs. Each of the 8 outputs
     corresponds to the logical value (0/1) of the first 8 bits and you
     feed these into the set of Indicators for display. The 8 formulas
     inside the UO would be - bit(A,0) - bit(A,1) - bit(A,2), etc.
        I hope this conveys the concept adequately.

Actually this is a bit simpler with VEE 4.0. You can put all thebit() functions in
a single formula, separated by semicolons, and
assign them to multiple output pins.

For example:

   b0 = bit(a,0); b1 = bit(a,1); ....

This is even easier in VEE 5.0 because you have multiline formulas:

   b0 = bit(a,0);
   b1 = bit(a,1);
   ...
