StringTools[IsSpace] - determine if a character is a space character
Calling Sequence
IsSpace(char)
Parameters
char
-
string; character to test
Description
The IsSpace(char) command determines whether char is a space character.
A space character is any one of the following:
Space Character
Meaning
ASCII Code
`` ''
space
32
``\t''
horizontal tab
9
``\n''
new line
10
``\r''
carriage return
13
``\f''

If char is a space character, IsSpace returns true. Otherwise, false is returned.
If char is a string that contains more than one character, then all the characters in the string are tested. The command returns true if the condition is true of all characters in the input string. For the empty string, the tested condition is vacuously true.
Thread Safety
The StringTools[IsSpace] command is thread-safe as of Maple 15.
For more information on thread safety, see index/threadsafe.
Examples
Important Note: The user should take care if attempting to copy the following example into a Maple session. Since the output from the following command contains control characters, unexpected results can occur on certain platforms. It is recommended that this example not be copied.
