how to remove char to num conversion note

[paddyb]

data demo;
A = 5;
B= '0';
c = A + B;
run;

[Doc_Duke]

data demo;
A = 5;
B= '0';
c = A + input(B, 1.0);
run;

You can't 'hide' that note without hiding lots of others.  Your best approach is to use good programming to begin with.

As @Doc_Duke has suggested, rather than letting SAS do the conversion on the fly (resulting in a Note), use one of a number of functions to perform the conversion directly.  There are functions that go both ways numeric --> Character and character --> numeric.

The INPUT family of functions (in @Doc_Duke's example) can yield a numeric, while the PUT family of functions yields character values.
