I can't believe that you are using that code really! Id like to see your
log for that. I think, some semicolons would help there.
Maybe something like that:
data x ;
set x ;
if variable lt 0 then delete;
run;
but in comparing chars with numerics, sometimes unexpected results may
occure.

expressions and conditions where its numerical value is needed. However,
SAS in such cases performs implicit type conversion (in memory) in order to
process the statement. But as you have text as values from the variable
('#n/a') that can not be converted appropriately and thus will not succeed.
You'll have to base your condition(s) upon the literal text(s), occurring
as a representation of missing values, thus '#n/a' or maybe '#N/A' or
even 'n/a' and the like as well if those values also occur. For SAS that is
just literal text without any known meaning. If you do not yet succeed in
deleting all records with what you defined as missing values for that
Variable then call again and provide some code and some sample data as well.
