two questions (looked thru the tutorial guides, but could not find any helpful examples) -
1. Is it possible to add a value to a symbolic constant where it defines an offset
eg, instead of
I would prefer (for readability) something that achieves :
2. Suppose I have a file with a column for year (say at 10,4) defined as type char (YYYY). I want to add a constant to the year value where the record matches some criteria, but leave the result as CHAR.
how can this be done within an OVERLAY ?
1. I'm not sure I understand what you're trying to do, but here's an example of using f2_c_p5 as a symbolic constant representing the position of f2_c + 5. Note that + is not allowed in symbols, so I used p5 (for plus 5) instead.
