OS/VS COBOL trace output sequence

The trace output sequence has changed under Language Environment. With Language Environment, only one trace entry per record appears, instead of numerous trace entries per record as in OS/VS COBOL. This is especially helpful with intervening DISPLAY SYSOUT output and error messages.

Figure 1 shows the differences between OS/VS COBOL and Language Environment.
