DIM("\n") return 1. (Notice the use of the two double

quotes and the escape sequence.)

STRING Syntax: STRING (object);

Returns a string representation of object. The result varies

depending on the type of object.

Examples:

INSTRING Syntax: INSTRING (str1,str2)

Returns the index of the first occurrence of str2 in str1.

Returns 0 if str2 is not present in str1. Note that the first

character in a string is position 1.

Examples:

INSTRING("vanilla","van") returns 1

INSTRING ("banana","na") returns 3

INSTRING("ab","abc") returns 0

LEFT Syntax: LEFT (str,n)

Return the first n characters of string str. If n ≥ DIM(str) or

n < 0, returns str. If n == 0 returns the string.

Example: LEFT("MOMOGUMBO",3) returns "MOM"

RIGHT Syntax: RIGHT(str,n)

String Result

string(F1), when F1(X)

= COS(X)

"COS(X)"

string(L1) when L1 =

{1,2,3}

"{1,2,3}"
