This script is designed to be used when there is a change of specimen or operator during a microscopy session. If the script 'Set Specimen and Operator Dialoglib' is installed as a library file, these two parameters will be prompted for when DM is first launched. The script shown here is then used to update the operator and specimen once a microscopy session is underway. This script is an updated version of an earlier script of the same name. It was changed so that it sourced the current operator and specimen from the Global Info, and provided these as defaults when entering new data - this saves retyping both parameters when only one (usually the specimen) needs changing.
