Answer 1

According to this Embarcadero docwiki page the A, C and B are for Alignment, Combination and "Big". It seems the page does not explain what the P means. The hex value is a mask, although as far as I can see it doesn't list all values. (The listed values don't allow for an odd value for instance)

Alignment

• 00 - An absolute segment
• 20 - A byte-aligned segment
• 40 - A word-aligned segment
• 60 - A paragraph-aligned segment
• 80 - A page-aligned segment
• A0 - An unnamed absolute portion of storage

Combination

• 00 - Cannot be combined
• 08 - A public combining segment

Big (for 16 bit)

• 00 - Segment less than 64 K
• 02 - Segment exactly 64K
