D

When necessary for clarity, the symbol D may be used

 

 

 

in a syntax statement to indicate a required blank or

 

 

 

an exact number of blanks. For example:

 

 

 

SET[(modifier)]D(variable);

underlining

When necessary for clarity in an example, user input

 

 

 

may be underlined. For example:

 

 

 

NEW NAME? ALPHA

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Brackets, braces, or ellipses appearing in syntax or

 

 

 

format statements that must be entered as shown will

 

 

 

be underlined. For example:

 

 

 

LET var[[subscript]] = value

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Output and input/output parameters are underlined.

 

 

 

A notation in the description of each parameter

 

 

 

distinguishes input/output from output parameters.

 

 

 

For example:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

CREATE (parm1,parm2,flags,error)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The symbol

 

may be used to indicate a key

 

 

 

 

 

 

 

on the terminal's keyboard. For example,

 

 

 

 

 

 

 

 

 

RETURN

 

 

 

 

indicates the carriage return key.

 

char

 

 

 

 

 

 

 

CONTROL

Control characters are indicated by

 

CONTROL

 

 

 

 

 

followed by the character. For example,

 

BY

 

 

 

CONTROL

means the user presses the control key and the character Y simultaneously.
