HELP: Write length and pointer formats to memory TYPE: OBJECT SYNTAX: VAR(METHOD=PLENPTR/ALENPTR/PPTRLEN/APTRLEN/PFLGLENPTR/PPTRLENFLG,ALIGN=num)
This object is used to write a column as certain length pointer structure to memory.
An alignment can be used to pad each cell to the next multiple of the specified byte count, so that the next column starts at a pre-defined offset.
NUMBER: METHOD=PLENPTR/ALENPTR/PPTRLEN/APTRLEN/PFLGLENPTR/PPTRLENFLG - Sets field order of buffer pointer and pointer length as well as padding [PFLGLENPTR]
