Macros are another means of entering source code quickly, and some features of Auto-Code are implemented with special macros.
Use macros to assign short character strings to commonly used snippets of code, so you enter the string and expand it into the code snippet. Macros can be simple, single line text substitutions such as ad and cn, or they can expand into complex multi-line code snippets, including replaceable parameters with default values.
Typical macros are invoked by entering the macro name and pressing Ctrl+P. The macro is expanded, only if the caret is immediately after the macro name, and the macro name is at the beginning of the line, or it contains at least one space before it.
