Type in the command. As you type each character, the corresponding character appears in the entry area, and the cursor advances to the next character position. When you reach the end of the first line of a two-line entry area, the cursor advances automatically to the first character position of the next line, so that you can continue the command. The maximum number of characters that you can enter is 126.
You have the option of entering one command or several commands.
To enter more than one command, use the MVS™ command
delimiter. The MVS command delimiter is defined during system
initialization in the CONSOLxx parmlib member. 
To set
the command delimiter after system initialization, use the SET CON=xx
command.
Most commands can be entered in either lowercase or uppercase. The system converts the commands to uppercase, if required. However, information within a command that is contained within single quotation marks (for example, a reply to a WTOR message) is not converted to uppercase by the system. If the system requires the information within the single quotation marks in uppercase, be sure to type it in uppercase when you enter the command. When an MVS command delimiter has been defined during system initialization, you cannot use the defined delimiter within single quotation marks.
