Introduced in the 1977 ANSI M[UMPS] language standard.

This metalanguage symbol represents an occurrence of an argument of the Do command. Examples of valid arguments for the Do command appear in an earlier section. The argument of the Do command is either a destination, or an indirection operator (@) followed by an expression that evaluates to a list (separated by commas) of such arguments.

Modified in the 1990 ANSI M[UMPS] language standard.

The argument of the Do command is either a destination, optionally followed by a parameter list, or an indirection operator (@) followed by an expression that evaluates to a list (separated by commas) of such arguments.

Modified in the 1995 ANSI M[UMPS] language standard.

The destination of a Do command may also be an external subroutine.

Approved for addition in a future M[UMPS] language standard.

The argument of the Do command may also be a method of an object.

Do word.Insert("Hello World.")
executes the method Insert of the object that is accessible through the value of local variable word.
