Using Fundamental REXX Elements


This section gives you a chance to try some of the elements used in 
writing REXX procedures.  Do not worry about making mistakes because you 
will be guided through the steps. 
Note:    When writing a REXX procedure, it is best to use one line for 
         each element. If you want an element to span more than one line, 
         you must put a comma (,) at the end of the line to indicate that 
         the element continues on the next line.  If you want to put more 
         than one element on a line, you must use a semicolon (;) to 
         separate the elements. 
         A REXX procedure can contain any or all of the following 
         elements: 
   o  Comments 
   o  Strings 
   o  Instructions 
   o  OS/2 Commands 
   o  Assignments 
   o  Labels 
   o  Internal Functions.
