As designed or a bug?

In noticed some unexpected behaviour:

Code: Select all

Function Options(*DIRECT)

Define Field(#value1) Type(*INT)
Define Field(#value2) Type(*INT)
Define Field(#value3) Type(*INT)

#value1 := 1
#value2 := 2
#value3 := 3

#value1 #value2 #value3 := #value1 + #value2 + #value3

Use Builtin(MESSAGE_BOX_ADD) With_Args(('value1: &1').substitute( #value1.AsString ))
Use Builtin(MESSAGE_BOX_ADD) With_Args(('value2: &1').substitute( #value2.AsString ))
Use Builtin(MESSAGE_BOX_ADD) With_Args(('value3: &1').substitute( #value3.AsString ))
Use Builtin(MESSAGE_BOX_SHOW)

Results in:

I would expect for the evaluation to take place, and after that the result being assigned to all 3 values. But it looks like it's evaluated like:

Value1 := 1 + 2 + 3
Value2 := 6 + 2 + 3
Value3 := 6 + 11 + 3

Is this as designed, or is this a bug?

Hi Peter,

Tis is "as desgned" I think. I saw same issues likes this in the past.

I will check for you.

This is the normal way the evaluation is done, once value1 is changed, the next eveluation will use the new value.

Thanks. Good to know that ASSIGN is executed for each variable in the list separately. The documentation doesn't mention this.
