BlockMove

Statement

✔ Appearance ✔ Standard ✔ Console

Syntax

BlockMove sourceAddr&, destinationAddr&, numberBytes&

Description

Copies a range of bytes which begin at address sourceAddr&, to the address range that begins at address destinationAddr&. The numberBytes& parameter specifies the number of bytes which are to be copied. The copying works correctly even if the source and destination ranges overlap.

Example

dim src%(79999), dst%(79999)            '80000-element arrays
'Copy one array to the other:
BlockMove @src%(0), @dst%(0), 160000

Notes

For copying small amounts of data (80 bytes or less) into a variable, it is more efficient to use the var;length = address syntax of the let statement. See the let statement for more details.
