MemMove

Purpose

Copies a block of memory

Syntax

MemMove dst, src, count

MemMove(dst, src, count)

Description

The first parameter of MemMove is the address of the destination and the second one the one of the source and the third one can be a constant or, for example, the length of the source to copy.

Example

Local a$ = "GFA Basic", b$ = Space(9)

MemMove V:b$, V:a$, 9            // This works as described

Print a$, b$

a$ = "GFA Basic", b$ = Space(9)

MemMove V:b$, V:a$, Len(b$)      // This doesn't work this way...

Print a$, b$

Local a% = 1234, b%

MemMove V:b%, V:a%, SizeOf(a%)

Print a%, b%

Remarks

MemMove is equal to BlockMove which can be used instead.

MemCpy is extremely efficient in copying Type variables. MemCpy is one of the rare commands that is compiled inline when count is a constant.
