MUMPS Commands

The following commands are the M language commands implemented in GT.M. All commands starting with the letter Z are GT.M additions to the ANSI standard command set. The M standard specifies standard abbreviations for commands and rejects any non-standard abbreviation

M commands may be abbreviated to a defined prefix. Most commands have arguments. However, some commands have either optional arguments or no arguments. When a command has no argument and is followed by more commands on the same line, at least two spaces (_ _) must follow the command without arguments. Commands that accept arguments generally accept multiple arguments on the same command. M treats multiple arguments the same as multiple occurrences of the same command, each with its own argument.
