SYMBOLGEN
Details
1. With SYMBOLGEN enabled, SAS presenets the results of the resolution of macro variables in the SAS log, it show the value of both automaci and user-defined macro variables.
2. Helps Debug SAS Program and it only displays macro variable values when they are referenced.
EXAMPLE
26 options symbolgen; 27 28 %let reptitle=Book Section; 29 %let repvar=section; 30 SYMBOLGEN: Macro variable REPTITLE resolves to Book Section SYMBOLGEN: Macro variable SYSDAY resolves to Tuesday 31 title “Frequencies by &reptitle as of &sysday”; 32 proc freq data=books.ytdsales; SYMBOLGEN: Macro variable REPVAR resolves to section 33 tables &repvar; 34 run; NOTE: There were 3346 observations read from the data set BOOKS.YTDSALES. NOTE: PROCEDURE FREQ used (Total process time): real time 0.15 seconds cpu time 0.01 seconds SYMBOLGEN: Macro variable REPTITLE resolves to Book Section SYMBOLGEN: Macro variable SYSDAY resolves to Tuesday 35 36 title “Means by &reptitle as of &sysday”; 37 proc means data=books.ytdsales; SYMBOLGEN: Macro variable REPVAR resolves to section 38 class &repvar; 39 var saleprice; 40 run; NOTE: There were 3346 observations read from the data set BOOKS.YTDSALES. NOTE: PROCEDURE MEANS used (Total process time): real time 0.01 seconds cpu time 0.03 seconds
mcompilenote=none/noautocall/all
Details
MCOMPILENOTE writes notes to the SAS log about whether a macro program compiles successfully
Arguments
none不会在日志中输出信息(default)
noautocall会在日志中输出非autocall macros的所有宏的信息
all输出所有信息
Example
1 options mcompilenote=all; 2 %macro mymacro; 3 %mend mymacro; NOTE: The macro MYMACRO completed compilation without errors.
OPTIONS MPRINT/NOMPRINT
Details
By default, SAS does not write to the SAS log SAS language statements submitted from within a macro program. If you want to see the SAS code that the macro processor constructs and submits, enable the MPRINT option.
the text that is sent to the SAS compiler as a result of macro execution is printed in the SAS log
Example
23 options mprint; 24 %prtlast MPRINT(PRTLAST): proc print data=WORK.SALES (obs=5); MPRINT(PRTLAST): run;
OPTIONS MPRINTNEST/NOMPRINTNEST
Details
Aligns the nesting level of macro programs and the SAS code generated by the execution of the macro programs in the SAS log.
OPTIONS MLOGIC | NOMLOGIC;
Details
The information written to the SAS log when MLOGIC is enabled includes the beginning and ending of the macro program and the results of arithmetic and logical macro language operations.
Example
/*红色字体为作用效果*/ options nomprint mlogic; 107 %prtlast MLOGIC(PRTLAST): Beginning execution. NOTE: There were 1 observations read from the dataset WORK.SALES. NOTE: PROCEDURE PRINT used: real time 0.02 seconds cpu time 0.02 seconds MLOGIC(PRTLAST): Ending execution.
OPTIONS MLOGICNEST | NOMLOGICNEST;
Details
Displays the nesting level of macro programs in the SAS log. This information is displayed in the MLOGIC output in the SAS log, and MLOGIC must be enabled for this option to work.
