I have an array data structure that has some varchar subfields, initialized with INZ(''). There is no space between the quotes, which appears to set the length to 0 for all rows. That's what I want. All's cool.
I then call a procedure that gets some values for two of the four subfields, and loads three rows with those values. That's cool too. What isn't so cool is the two fields that should be untouched by the called procedure get blank-filled, and I don't know why, or how best to prevent that. I could spin through a for-loop and load the target DS from the results of the called procedure, but I thought I might not have to.
