Concatenation operator in PowerBuilder

Description

The PowerBuilder concatenation operator joins the contents of two variables of the same type to form a longer value. You can concatenate strings and blobs.

The following table shows the concatenation operator.

Operator	Meaning	Example
+	Concatenate	`"cat " + "dog"`

Examples

Example 1 These examples concatenate several strings:

string Test

Test = "over" + "stock" // Test contains "overstock"

string Lname, Fname, FullName

FullName = Lname + ', ' + Fname

      // FullName contains last name and first name,

      // separated by a comma and space.

Example 2 This example shows how a blob can act as an accumulator when reading data from a file:

integer i, fnum, loops

blob tot_b, b

. . .

FOR i = 1 to loops

 bytes_read = FileRead(fnum, b)

 tot_b = tot_b + b
