&&= - Calculation Assignment

Other versions: 7.31 | 7.40 | 7.54

Syntax

lhs &&= rhs.

Effect

Calculation assignment with the string assignment operator &&=.

This assignment works in the same way as the following assignment of a string expression:

lhs = lhs && rhs.

The result of the expression rhs is concatenated with the content of lhs and the result is assigned to lhs.

The following applies to the operands lhs and rhs:

• lhs is a result position and the following can be specified (if character-like):
  

• Variables

• Writable expressions

• rhs is a character-like expression position and the following can be specified (if character-like):
  

• Data objects

• Constructor expressions

• String expressions

• Table expressions

• Functions

Type inference with the character # is not currently possible in constructor expressions. Numeric expressions and bit expressions cannot be specified.

Notes

• No inline declarations are possible for lhs.
• Calculation assignments can currently only be specified as standalone statements. They cannot be used in expressions, for example after NEXT in the reduction operator REDUCE.
• See also the addition assignment operator (+=), the subtraction assignment operator (-=), the multiplication assignment operator (*=), and the division assignment operator (/=).
  

Example

After the calculation assignments the variable text has the value 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,.

DATA text TYPE string. 
DO 10 TIMES. 
  text &&= |{ sy-index }, |. 
ENDDO.
