In 4D, numeric values displayed inside a form are displayed as a decimal value by default. There are a couple ways to display numeric values as hexadecimal inside of a form variables:

1.) Use a string representation to display the hexadecimal value.

The 4D command STRING takes in an optional 2nd parameter for format. The value passed to this parameter should be "&x". See the example below:

vDec:=10                //numeric value vHex:=String(vDec;"&x") //hexidecimal alpha representation of the numeric value

2.) Use a display filter to filter the results. This will allow the variable to be of numeric type.

To add a display filter, click on the variable to bring up the properties list. Under the Number Format option click on the button "..." to bring up the filter editor:


Add a filter with the following definition: "&x":


In the properties list, select the new filter for the Display Format:


The variable will now display numbers as its hexdecimal:
