General statement syntaxThe general syntax of a statement is: Delete row from connected non-graphic database. Add row to connected non-graphic database.

A statement without a label must be indented with spaces, tabs, or both. UCM StatementsMany operators have associated operands, which further specify the action, and a label, which identifies the statement for branching operations. There are many types of operators, and the name of each operator indicates the action to be taken by MicroStation. Each statement has one and only one operator, which directs MicroStation to take action.

UCM StatementsA UCM consists of a series of statements. User Command Macros are unrelated to MicroStation BASIC programs (which are occasionally referred to as Macros). See Adapting IGDS UCMs for MicroStation on page 15-33 for a list of the differences. The UCM language and registers are essentially the same for MicroStation and the VAX-based IGDS system. You need to know about commands only if you are customizing MicroStation. A UCM can be thought of as a sequence of MicroStation commands (although this is an oversimplification).
For example, the Place Helix tool activates the PLACE HELIX command. In MicroStation, every tool, view control, or key-in activates a command. You can use UCMs to: Automate common sequences of tool usage and key-ins. The information in this chapter is provided to enable you to convert existing UCMs to current analogs. For this reason, no future enhancements to the UCM functionality are planned. However, MicroStation 95s increased flexibility and ease of use now enable you to perform many simple functions for which you may have used UCMs in the past. 15 User Commandsucmlang.pdf User Commands (UCMs) are macros that follow the logic and syntax rules of the UCM language described in this chapter.
