Description
Copies data as individual bits, so the new location does not have to
be the same data type. Data can be moved into a different data type
without prior conversion.
Provides an input that allows for data coherency by locking symbolic
memory being written to during the copy operation.
Provides the option of locking the symbolic or I/O variable memory
area being written to during the copy operation.
Copies data from symbolic or I/O variable memory to reference
memory. Copies across mismatching data types.
Shifts one or more data bits, data WORDs or data DWORDs from a
reference location into a specified area of memory. Data already in
the area is shifted out.
Counts the number of bits used by a variable.
Swaps two BYTEs of data within a WORD or two WORDs within a
DWORD.
