box will be displayed, allowing you to choose a register within that remote communications

property. However, they can also be edited by pressing the Edit button next to the field,
thereby activating a dedicated dialog box that allows more of the expression to be seen…

therefore provides syntax coloring. You can also access help information on system functions
by placing your cursor in or at the end of the function name and pressing F1.
COMPLEX EXPRESSIONS
If your expression is too complex to fit into a single line—or if you would simply rather write
