Undocumented Delphi record alignment directive – Chee Wee’s blog: IT solutions for Singapore and companies worldwide

Reading a thread with ramblings on failing to understand that packed records overrides the $ALING directive, I found out that there is also an Undocumented Delphi record alignment directive – Chee Wee’s blog: IT solutions for Singapore and companies worldwide.
David Heffernan mentioned some nice permutations in the first thread.Chee Wee Chua “documents” the second. Both provide great reference material.
Note that both directive require a const expressions evaluating to a power of two. If you don’t, you get the same error: E2573 Illegal value for the ALIGN directive (valid for one of 1, 2, 4, 8 or 16) (Delphi) – RAD Studio
