I'll start by defining a string variable, so I'll call it str1, equals, and then in single quotes, card, and Enter. So there's my assignment. Let's say I want to check to see if this is a character string, so str1 is a character string. I would use ischar, followed by left parentheses and str1, the name of the variable.
