Concatenation of serial bytes

Read(320) Label: serial bytes,

Here’s how to use k1+k2 function for concatenating serial bytes.

k1+k2

Description:

Concatenate serial bytes.

Syntax:

k1+k2

Note:

Concatenate serial byte k1 and serial byte k2; both k1 and k2 must be serial bytes.

Parameters:

k1

A serial byte

k2

A serial byte

Return value:

A serial byte

Example:

k(1)+k(3:2)

65539

 

k(1:2)+k(1,3,4)

16843524

 

 

Serial bytes concatenation in a composite table:

 

 

 

 

A

 

 

1

=create(k1,v1).record([k(1:3),10,k(2:3),20,k(3:3),30,k(4:3),40,k(10:3),100])

Create a table sequence where k1field is serial byte data

 

2

=create(k1,k2,v2).record([k(1:3),k(1:2),"a",k(2:3),k(4:2),"c",k(2:3),k(8:2),"b"])

Create a table sequence where k1field and k2 filed are serial byte data

 

3

=file("D:/ckv2.ctx")

A composite table file

 

4

=A3.create(#k1:3,v1)

Create the composite table’s base table where k1 field is serial byte data

 

5

=A4.attach(table2,#k2:2,v2)

Add attached table table2 to the base table, where k2 field is serial byte data

 

6

=A4.append(A1.cursor())

 

 

7

=A5.append(A2.cursor())

 

 

8

=A5.cursor(k1+k2).fetch()
