Torben,

I assume your intercept is not a variable name in a dataset. If it would be and you would use SAS vs. 8 (which I don't have) than I would not expect that error, for AFAIK variable names longer than 8 characters are allowed in vs. 8.

So I expect it to be ( and intended as such) just a text. In macro statements text needs not to be qouted (macro language is only textprocessing). However in a normal data step such text should be qouted and thus your statement if &intercpt = intercept then pp=p+1; * this would compare variables; should read: if "&intercpt" = "intercept" then pp=p+1; * this compares values; It is necessary to use the double quote, because otherwise the macro variable &intercpt would not be resolved.

I hope this is clear.

My computer now is used long enough to the year trap.
