MOVEBLOCK
Inputs
SRC: ANY (*) Array containing the source of the copy
DST : ANY (*) Array containing the destination of the copy
PosSRC: DINT Index of the first character in SRC
PosDST : DINT Index of the destination in DST
NB : DINT Number of items to be copied
(*) SRC and DST cannot be a STRING
Outputs
OK : BOOL TRUE if successful
Remarks
Arrays of string are not supported by this function.
In FFLD language, the operation is executed only if the input rung (EN) is TRUE. The function is not available in IL"Instruction list" This is a low-level language and resembles assembly language.
The function copies a number (NB) of consecutive items starting at the PosSRC index in SRC array to PosDST position in DST array. SRC and DST can be the same array. In that case, the function avoids lost items when source and destination areas overlap.
This function checks array bounds and is always safe. The function returns TRUE if successful. It returns FALSE if input positions and number do not fit the bounds of SRC and DST arrays.
