Copy Channel with Mask

Use the Database Tools > Channel Tools > Copy Channel with Mask menu option (COPYMASK GX) to copy one channel to another, using a mask channel to set values.

Copy Channel with Mask

Copy from	Original channel. Script Parameter: COPYMASK.FROM
Copy to	Destination channel (can be same as original channel) Script Parameter: COPYMASK.TO
Mask channel	Mask channel. Value which are dummies will mask the original channel values. If the mask channel value is not a dummy, the data value is copied as normal. Script Parameter: COPYMASK.MASK

Application Notes

If a new channel does not exist, it will be created with the same definition as the original channel. Where the mask channel value is a dummy "*", the copied value will be set to a dummy; otherwise the data is copied as is, subject to the usual rule on data conversion if the original and destination channels are different types.
