MLOGIC | NOMLOGIC

Syntax Description

MLOGIC: specifies that the macro language processor trace its execution and write the trace information to the SAS log.
NOMLOGIC: specifies that the macro language processor not trace execution or write to the SAS log.

Details

Use MLOGIC to debug macros. If MLOGIC is in effect and the macro processor encounters a macro invocation, the macro processor displays messages that identify

the beginning of macro execution
the values of macro parameters at that point
the execution of each macro program statement
whether each %IF condition is true or false
each iteration of the %DO loop
the end of macro execution.

CAUTION:: MLOGIC can produce a great deal of output in the SAS log.
