If you include the comment before or in the middle of a CLIST statement or TSO/E command, you must end the comment with a closing comment delimiter (asterisk-slash). The following example shows a comment included before a CLIST statement:

/*get return code */ SET RC = &LASTCC

If you include a comment after a CLIST statement or TSO/E command, or on a line by itself, the closing comment delimiter is not needed, as shown in the following example:

alloc file(in) da(accounts.data) shr /* Input data set
