The below SAS program shows the use of character functions.data character_functions; /* Convert the string into lower case */ lowcse_ = LOWCASE('HELLO'); /* Convert the string into upper case */ upcase_ = UPCASE('hello'); /* Reverse the string */ reverse_ = REVERSE('Hello'); ...
The system function executes a character string as a command by passing it to an operating-system-defined command processor. The cmd argument is a pointer to the command string, which consists of two parts: a prefix that contains an optional command type followed by a colon and a command. ...
A FUNCTION returns a value from a computation or system manipulation that requires zero or more arguments. And, like most programming languages, the SAS System provides an extensive library of "built-in" functions. SAS has more than 190 functions for a variety of programming tasks. This ...
