Structure Pointer
Structure Pointer
A structure pointer redefinition associates a new structure pointer with a previous item
at the same BEGIN-END level of a structure.
VOLATILE
specifies that the value of this variable must be maintained in memory, not in a
register. Each reference to a VOLATILE data item causes the data item to be read
or written to memory even when code is optimized. Based on the order of reads
and writes in the source code, VOLATILE also causes that precise order of
memory references to be preserved, again, when code is optimized.
STRING
is the STRING attribute.
INT
is the INT attribute.
