This metalanguage symbol represents the special character "Form Feed". Since this character is normally not visible in printed text, the representation FF is used in the ANSI M[UMPS] language standard to indicate that this special character is present in a specific location.
Starting from the 1990 ANSI M[UMPS] language standard, this symbol is spelled as FF (underscored).

This metalanguage symbol represents a numeric value that indicates the maximum width of a character in a font.
Introduced in the 1995 ANSI M[UMPS] Windowing Application Programmer's Interface standard.
This metalanguage symbol represents a numeric value that identifies the size of displayed text in points. A point is 1/72 inches.
Introduced in the 1995 ANSI M[UMPS] Windowing Application Programmer's Interface standard.
This metalanguage symbol represents one or more codes that describe the display characteristics of text. This metalanguage symbol occurs as an expression that evaluates to a list of codes (separated by commas). The individual codes can be either one of "NORMAL", "BOLD", "ITALIC" or "ULINE", or to an implementation-specific value (starts with "Z"). The value "NORMAL" cannot be combined with any other value in a list (i.e. must occur alone).
Introduced in the 1990 ANSI M[UMPS] language standard.
This metalanguage symbol represents a line in a routine that starts with a label that carries a formal parameter list. This type of line may not have level indicator marks (periods) following its line start white space.
Introduced in the 1990 ANSI M[UMPS] language standard.
This metalanguage symbol represents the formal parameters that are specified following the defining occurrence of the label that starts the subroutine or function to which parameters are passed (formal parameter list: at the label of the invoked subroutine or function; actual parameter list: in the call to that subroutine or function).

Examples:
#
!
?5
#!!!!!?25
###
#?5
Note: The format specification itself does not allow for indirection, but a format specification is an argument of a READ or WRITE command, and that argument may be indirected. As a result:
is a valid way to create a variable number of line feeds.
Addition in the 1995 ANSI M[UMPS] language standard.
Formatting specifications may also include device control functions (see the metalanguage symbol controlmnemonic).
Examples:
WRITE /CUP(20,5),"Header goes here"
WRITE /SGR(1),"This appears in boldface"
Introduced in the 1977 ANSI M[UMPS] language standard.

FOR K="ABC","klm","PQR"
FOR K=1:3
In the last example, unless an explicit QUIT command is executed within the scope of the FOR loop, the loop will continue forever.
