• n_statement, s_statement : n stands for numeric, s stands for string.
• LeIement, r_element : I stands for left, r stands for right.
• Uppercase and lowercase letters are not distinguished from each other except in
string constants. For example, curpos and
CURPOS
are interchangeable.
• One or more blanks may be inserted between tokens. However, when
no
ambigu-

is
possible, blanks are not required. For example, 1 + 2
is
a legal expression.
