The other kind of Pi

Question

Diademm 9.10.2160 SP 1b
Try this DAC and look the result.
Dac-Script original :
Dim Pi : Pi = 3.14
Sub SFD_ReadChannel( ChannelNumberP, ParamP, DataP, ErrorP )
  DataP = Pi
End Sub
and modification:
Dim Pi_ : Pi_ = 3.14
Sub SFD_ReadChannel( ChannelNumberP, ParamP, DataP, ErrorP )
  DataP = Pi_
End Sub
The predefined
VBS-constant Pi is unknown in DAC-Script. But not compleed unknown? In
first script the script interpreter seems to remember the Pi
-predefinition, but it makes a mistake in converting the decimal sign,
or what's going on here?

Hi Bohm,
Yes this was hard to understand. The upcoming DIAdem version will have the following note in the help:
Note: You cannot use DIAdem commands in the Script DAC driver. You only can access DIAdem variables in the read mode. To do so you must declare the DIAdem variables using Dim, in the global section of the script. DIAdem then copies the current contents of the DIAdem variables onto these script variables.
Thank you,
Ralf
