Continue On If Certain Error Message

I have a sql statement which runs through a reference table to drop columns no longer needed. It works, however if it tries to delete a column that does not exist, it errors out. Is there a way to continue if this error appears(I have the set error routine set up) The question is can I tell it if it is this error to go on, and is "continue" the
right syntax? Below is statement

open dbcursor
fetch next from dbcursor into @tbname,@fldname,@recid
while (@@FETCH_STATUS <> -1)
begin
--set @tbname = 'IMMUNIZATION_MAST_'
--set @fldname = 'cb_other'
set @sql = 'alter table ' + ltrim(@tbname)
set @sql3= ' drop column ' + ltrim(@fldname)
exec(@sql + @sql3)
select @error = @@error
if @error = 5924
begin
CONTINUE?
end
print @error
