Re: Referring to a Column

EVAL() is pretty brief.

Consider standardizing the alias, for example,

USE (aliasstr) alias TARGET AGAIN IN 0

Now, the report can refer to Target.fieldname with no need to wrap it in a function.

Of course, the actual problem you're trying to solve might be more complex. Please share.

Hello:

 Suppose I wish to refer to a column.  I have the alias in *text* form.

What is the best way to access the column? By best, I mean a short, clear way that:

1. can be used in both reads or writes on the column and
2. is in-line: I do not want to have to define a variable with an

expression and then use that in a later line.

 I have the rather ugly
      evaluate(aliasasstr+".colname")

which I have used for years on occasion. Now, I am modifying a report where I will have to use this sort of access more than a few times.

 Am I overlooking something cleaner?
