I'm afraid I can't answer your question: I'm also working on Ruby to SAP, but have settled on the RFC route.

| | | |   | | 204198 [perrin apoth] That might be the "part that counts" (nice pun) for calculation, but

| | | | + 204005 [headius head] Doubt all you like.
| | | |   + 204019 [sean.ohalpin] While I accept that you shouldn't confuse a language with its implementation,

| | | |   | + 204034 [headius head] Garbage collection is a characteristic of the Java VM, not the language.
| | | |   | | 204092 [perrin apoth] In some ways, you're right: implementation details are being mixed up
| | | |   | | 204169 [sean.ohalpin] Nope - there's no mix up. My point is that any feature of a language

|   |   + 204212 [garbagecat10] The problem isn't the raw size of the dataset. It's the number of

|   |   204424 [perrin apoth] How do you figure?  You just reiterated, in different words, everything

|   |   204676 [kmgaughan ei] I was being polite until you made a passive agressive remark about me
