6.12 Example of LRC calculations

Following is an example of calculating LRC with VisualBasic6.0.

Variables are declared as shown below.

VisualBasic6.0 cannot use code-free variables. It therefore uses code-equipped 16-bit integer

variables as data. Similarly, the LRC calculation results are entered into code-equipped 16-bit

integer variables.

Dim LRC As Integer

Dim i, arry_count As Integer

Dim lrc_arry(128) As Integer

Then enter calculable data into the 1rc_arry(), and enter the number of data items

into the arry_count

After that, run the following program to cause the calculation results to enter the LRC.

For i = 0 To arry_count

LRC = (LRC + lrc_arry(i)) And &HFF

LRC = ((Not LRC) + 1) And &HFF

If the error code is calculated as 12H as an example, affix a "1" or "2" at the end of the message.

1 2 ... 29 30 31 32 33 34 35 36 37 38 39 40 41 42
