This metalanguage symbol represents a display attribute. Such an attribute is identified by an expression that evaluates to one of "BCOLOR", "CLIPBOARD", "COLOR", "COLORTYPE", "FCOLOR", "FOCUS", "KEYBOARD", "PEN", "PLATFORM", "PRESOURCE", "PTR", "SIZE", "SPECTRUM", "TYPEFACE", "UNITS", or to an implementation-specific value (starts with "Z"), or to an application-specific value (starts with "Y").
To be modified in a future ANSI M[UMPS] Windowing Application Programmer's Interface.
The values "FFACE", "FSIZE", "FSTYLE", "PTYPE", "TBCOLOR" and "TFCOLOR" are added to the list of possible attribute codes.
Approved for inclusion in a future ANSI M[UMPS] language standard.
This metalanguage symbol represents the value of one of the directives of the FORMAT library function. The value represented by this metalanguage symbol is the "decimal separator character", a single character that is used to separate the integer parts from the decimal fractions in numbers.
Introduced in the 1977 ANSI M[UMPS] language standard.
The defining occurrence of a label is the occurrence in a routine where the label is specified (left of the line start white space). In any routine, any specific label may occur at most once in a defining occurrence.
Introduced in the 1995 ANSI M[UMPS] language standard.
The error code for multiple defining occurrences of the same label is M57.
Introduced in the 1977 ANSI M[UMPS] language standard.
A variable has a name and optionally subscripts.
When two variables have the same name, and one has more subscripts than the other, while all subscipts that the one with lesser subscripts has occur in the other variable with the same variable, then the variable with more subscripts is called a descendant of the variable with less subscripts.
For example, assume that the following elements of Y are defined:
Y(0)=0
Y(1)=1
Y(1,2)=2
Y(1,2,3)=123
Then Y(1,2,3) is a descendant of Y, of Y(1) and of Y(1,2), but not of Y(0) and Y(1,2) is a descendant of Y and Y(1).

Instead of the just the simple expressions, there may be device parameters. If a device parameter is a simple expression, its meaning is still implementation-specific. If a device parameter is a keyword or a keyword=value combination, its meaning is standardized and portable.

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.
