MACRO: MPRINT incorrect macro value parameter

KevinViel — Tue, 13 Sep 2016 14:43:17 GMT

I found this little curiousity today:

1589 %macro m_r_options_pagelayout

1590 ( topmargin = 0.375in

1591 , leftmargin = 0.750in

1592 , rightmargin = 0.375in

1593 , bottommargin = 0.375in

1594 ) ;

1595

1596 options orientation = portrait

1597 topmargin = &topmargin.

1598 leftmargin = &leftmargin.

1599 rightmargin = &rightmargin.

1600 bottommargin = &bottommargin.

1601 ;

1602

1603 %mend m_r_options_pagelayout ;

1604

1605 options mprint ;

1606 %m_r_options_pagelayout( )

MPRINT(M_R_OPTIONS_PAGELAYOUT): options orientation = portrait topmargin = 0.375

leftmargin = 0.750 rightmargin = 0.375 bottommargin = 0.375 ;

1607

1608 options nomprint ;

1609 %put %m_r_options_pagelayout( ) ;

options orientation = portrait topmargin = 0.375in

leftmargin = 0.750in rightmargin = 0.375in bottommargin

= 0.375in

Notice that the MPRINT of the macro call OMITS the in (inches). Does anyone explanation? Note that this is not SAS stripping off IN because that is the default units for this options:

1621 %m_r_options_pagelayout

1622 ( topmargin = 0.375cm

1623 )

MPRINT(M_R_OPTIONS_PAGELAYOUT): options orientation = portrait topmargin = 0.375

leftmargin = 0.750 rightmargin = 0.375 bottommargin = 0.375 ;

v9.4

Operating System: WX64_SV .

Thank you,

Kevin

It is storing the units. It is just MPRINT output that is miss leading.

It does it with SAS 9.2 also.

However note that if you run Proc Options the units do appear. An interesting artifact though.

In SAS 9.4 TS1M3 similar behaviour.

MPRINT strips the units but they are being resolved properly via Symbolgen.

See: http://www.pharmasug.org/proceedings/2016/TT/PharmaSUG-2016-TT17.pdf

MFILE captures the WRONG value, too:

%m_debug_mfile

( mcall = m_r_options_pagelayout( topmargin = 0.5cm ))

options orientation = portrait topmargin = 0.5 leftmargin = 0.750 rightmargin = 0.375 bottommargin = 0.375 ;

This would be 0.5in NOT 0.5cm, since in is the default.

No, it gets set properly, how MPRINT displays is the issue. You can check the value of the option set:

%put topmargin= %sysfunc(
     getoption(topmargin));
