2: Spin Language Reference – WORDMOVE
WORDMOVE
Command: Copy words from one region to another in main memory.
((PUB ┆ PRI))
WORDMOVE (DestAddress, SrcAddress, Count )
• DestAddress is an expression specifying the main memory location to copy the first
word of source to.
•
SrcAddress is an expression specifying the main memory location of the first word of
source to copy.
•
Count is an expression indicating the number of words of the source to copy to the
destination.
Explanation
WORDMOVE is one of three commands (BYTEMOVE, WORDMOVE, and LONGMOVE) used to copy blocks
of main memory from one area to another.
WORDMOVE copies Count words of main memory
starting from SrcAddress to main memory starting at DestAddress.
Using WORDMOVE
WORDMOVE is a great way to copy large blocks of word-sized memory. For example:
VAR
word Buff1[100]
word Buff2[100]
PUB Main
wordmove(@Buff2, @Buff1, 100) 'Copy Buff1 to Buff2
The first line of the Main method, above, copies the entire 100-word (200-byte) Buff1 array to
the
Buff2 array. WORDMOVE is faster at this task than a dedicated REPEAT loop.
