MID Syntax: MID(str,pos, [n])

Extracts n characters from string str starting at index pos. n is optional, if not specified, extracts all the remainder of the string.

Example: MID("MOMOGUMBO",3,5) returns "MOGUM", MID("PUDGE",4) returns "GE"

ROTATE Syntax: ROTATE(str,n)

Permutation of characters in string str. If 0 <=n < DIM(str), shifts n places to left. If –DIM(str) < n <= –1, shifts n spaces to right. If n > DIM(str) or n < –DIM(str), returns str.

Examples:

ROTATE("12345",2) returns "34512" ROTATE("12345",-1) returns "51234" ROTATE("12345",6) returns "12345"

STRINGFROMID Syntax: STRINGFROMID(integer)

Returns, in the current language, the built-in string associated in the internal string table with the specified integer.

Examples:

STRINGFROMID(56) returns “Complex” STRINGFROMID(202) returns “Real”

REPLACE Syntax: REPLACE(object1, start, object2)

Replaces part of object1 with object2 beginning at start. The objects can be matrices, vectors, or stings.

Example:

REPLACE("12345",”3”,”99”) returns "12995"

Drawing

There are 10 built-in graphics variables in the HP Prime, called G0–G9. G0 is always the current screen graphic.

G1 to G9 can be used to store temporary graphic objects (called GROBs for short) when programming applications that use graphics. They are temporary and thus cleared when the calculator turns off.

Twenty-six functions can be used to modify graphics variables. Thirteen of them work with Cartesian
