CONVENTIONS USED IN THIS MANUAL
NOTATION DESCRIPTION
nonitalics Words in syntax statements which are not in italics must
be entered exactly as shown. Punctuation characters
other than brackets, braces and ellipses must also be
entered exactly as shown. For example:
EXIT;
italics Words in syntax statements which are in italics denote a
parameter which must be replaced by a user-supplied
variable. For example:
CLOSE
filename
[ ] An element inside brackets in a syntax statement is
optional. Several elements stacked inside brackets
means the user may select any one or none of these
elements. For example:
[A] User
may select A or B or neither.
[B]
{ } When several elements are stacked within braces in a
syntax statement, the user must select one of those
elements. For example:
{A}
{B} User
must select A or B or C.
{C}
... A horizontal ellipsis in a syntax statement indicates
that a previous element may be repeated. For example:
[, itemname ]...;
In addition, vertical and horizontal ellipses may be
used in examples to indicate that portions of the
example have been omitted.
Å When necessary for clarity, the symbol ~ may be used in
a syntax statement to indicate a required blank or an
exact number of blanks. For example:
SET[(
modifier )]Å( variable );
underlining When necessary for clarity in an example, user input may
be underlined. For example:
NEW NAME? ALPHA
