The action of Compaq COBOL on OpenVMS Alpha with this qualifier is designed to closely match the default action
with Compaq COBOL for OpenVMS VAX. This qualifier is not available on Windows NT.
/ALIGNMENT=PADDING, -align padding
The Compaq Alpha Calling Standards require that data fields be aligned on
specific addresses (shown in those standards). The same standards specify that
the lengths of all data records and group data items must be multiples of their
alignments.
If /ALIGNMENT=PADDING or
-align padding
is present on the compile
command line, COBOL group data-items will be aligned on their natural
boundaries and those group items will be padded out to multiples of their
alignments. See the Compaq COBOL Reference Manual for detailed information
about elementary data item alignment with Alpha alignment and padding in
effect.
B.3.3 Qualifiers Only on Compaq COBOL for OpenVMS VAX
Table B–4 lists the command-line qualifiers and qualifier-option combinations
that are specific to Compaq COBOL for OpenVMS VAX. These are not available
in Compaq COBOL, and there are no equivalent flags.
