My first guess is that the input is not properly terminated (end of file) in the first example. In the second example, the input is terminated by statement 83, which has slashes in columns 1 and 2.
Assuming the wasn't an email formatting snafu, the input data steam appears to consist of two records. Had the '/*' appeared in columns one and two instead of two and three, the result may be different and may work as desired. As a personal habit, I like to terminate a job stream with a statement with // in one and two, and blanks in three on. HTH and good luck. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Anton Britz Sent: Tuesday, August 12, 2008 2:42 PM To: [email protected] Subject: zOs 1.7 JCL concatenation question ?
