OCT(<string expression>)
Returns the decimal equivalent of the string expression, which
should be a valid octal number.
Examples:    OCT("377")    OCT(OCTADR$)

* OCT$(<numeric expression>)
Returns a string which represents the octal value of the numeric
expression.  Examples:  OCT$(10)    OCT$(X+Y)    OCT$(DECIMAL)

PEEK(<numeric expression>)
Returns the value of the byte in memory address <numeric expression>.
Examples:  PEEK(0)    PEEK(1024+OFFSET)    PEEK(DECIMALADDRESS)

POS(<expression>)
Returns the current position of the PRINT device.  If used within a
PRINT statement, zero will always be returned, since the function is
evaluated before the line is printed.  This function is normally used
after a PRINT statement ending with a semicolon.
Examples:  POS(0)    POS("")    POS(anything)

RIGHT$(<string expression>,<numeric expression>)
Returns the rightmost <numeric expression> characters of
<string expression>.    Examples:  RIGHT$(SENT$,1)    RIGHT$(S$,NUM)

RND(<numeric expression>)
If <numeric expression> is less than zero, starts a new sequence of
random numbers.  If it's equal to zero, returns the same number as
the last RND returned.  If it's greater than zero, returns the next
random number in the sequence. 
Examples:    RND(-1)    RND(0)    RND(1)    RND(X)

SEARCH(<string expression>)
Searches the current disk file from the current position, for
the first (or next) occurance of <string expression>.  Returns
the number of carriage-returns + 1 that it passed while searching.
Examples:   PRINT SEARCH(A$+B$)   MOVEBOF:X$=SEARCH(INDEX$)

SGN(<numeric expression>)
If <numeric expression> is greater than zero, returns 1.
If it's equal to zero, returns 0; if less than zero, returns -1.
Examples:  SGN(-2.57)    SGN(0)    SGN(353.2)    SGN(X^3+Z)

SIN(<numeric expression>)
Returns the sine of angle <numeric expression>, which is in radians.
Examples:  SIN(DEG*PI/180)    SIN(.256)    SIN(X/Y)

SPACE$(<numeric expression>)
Returns a string of <numeric expression> spaces.
Examples:  SPACES$(BUFFERSIZE)    SPACES$(4+LEN(LINE$))

SPC(<numeric expression>)
Prints <numeric expression> spaces on the PRINT device.
Examples:  SPC(20)    SPC(N/3)    SPC(INT(X*2))
