Hi,

is it possible in phoebus to define a macro for a widget that calculates its value based on an input macro?

Assume I have defined a macro J that has the value 0. For the Widget I define a macro I that schould take the result of ${J} + 1.

Background: I need to create a screen that contains the 512 rows of a table with 4 columns. I have a single row defined in a file and created another file with a group of 32 rows.
Now for each of these rows I want to define I that runs from J to J+31.  So in the final screen I will have 16 embeded Displays of the block with J=0,32,64,96,...

Is t6here a way to format the macro definition such that it is not interpreted as a string, but evaluated as an expression?

Regards,

Jörn
