Shift - Maple Help

StringTools

 Shift
 shift the characters in a string by a given amount

 Calling Sequence Shift( s, shift )

Parameters

 s - Maple string shift - integer; shift amount

Description

 • The Shift( s, shift ) command shifts the characters in a string s by the amount given by shift. The value of shift can be positive, negative, or zero. If the value of shift is zero modulo $256$, the original string is returned unchanged.
 • All of the StringTools package commands treat strings as (null-terminated) sequences of $8$-bit (ASCII) characters.  Thus, there is no support for multibyte character encodings, such as unicode encodings.
