string; character to test

Description

• 

The IsGraphic(char) command determines whether char is a graphic character. Graphic characters consist of the alphanumeric characters and the punctuation characters. (For more information, see IsAlphaNumeric and IsPunctuation.)

  

If char is a graphic character, IsGraphic 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[IsGraphic] command is thread-safe as of Maple 15.

For more information on thread safety, see index/threadsafe.
