Question Evaluatin of fields

[Ines]

Hello,

Please, help me to find the best solution for evaluation a field value, which contains other fields in expression.

For simple example:

FieldA = 100
FieldB= FieldA * 2
FieldC = FieldB + 30

Thanks!

It looks like you are trying to parse an expression, so the shunting yard algorithm and reverse polish notation is what you are looking for. Of course you need to replace the variable names with their values at some point in the parsing.
