If you would like to run VIMAGE on a number of images (i.e. multiple rasters and vectors) you would need to implement a batch script. An example of a batch python script is outlined in this tutorial: https://support.pcigeomatics.com/hc/en-us/articles/207707003-Creating-a-Batch-Workflow-Pansharpening- . This tutorial include the Pansharp function but you could also run a similar script with VIMAGE. If you are encountering a specific problem in the script you can contact email@example.com.
Please note that the Developer Zone includes many tutorials, videos and example scripts to help users with developing python scripts with Geomatica: http://dev.pcigeomatics.com/developer-zone
