cmiss(of _all_)

[Patrick]

Hi

Why equals "cmiss(of _all_)" to the number of missing variables plus 1. (SAS 9.2 TS Level 2M3, X64 VSPRO).

data have;
a=1;b=.; c='x'; output;
a=.;b=.; c=' '; output;
a=.;b=.; c='x'; output;
run;

data test;
set have;
x= cmiss(of _all_);
put x=;
run;

Thanks

set have;
x= cmiss(of _all_);

everything from HAVE + X.

Think about it.

.... oh!?

Thanks data _null_; I wouldn't have thought about this.
