Description
|
|
•
|
The SubString(s, r) command returns a substring of string s specified by range r. A substring is a sequence of characters that occurs contiguously in the original string from which it is selected.
|
|
The range r must have integer endpoints. Range indexing for this function is similar to substring selection via the notation. For more information about range indexing, see selection.
|
•
|
The main difference between Substring and the Maple built-in substring procedure is that, when presented with a symbol as the first argument, substring returns a symbol while SubString returns a string.
