1.9.3 Concatenation of strings (<<)
Function
The function "concatenation strings" allows a string to be configured from individual
components.
The concatenation is realized using the operator "<<". This operator has STRING as the
target type for all combinations of basic types CHAR, BOOL, INT, REAL, and STRING.
Any conversion that may be required is carried out according to existing rules.
Syntax
<any_type> << <any_type>
Significance
<any_type>: Variable, type CHAR, BOOL, INT, REAL or STRING
<< : Operator to chain variables (<any_type>) to configure a character string
(type STRING).
This operator is also available alone as a so-called "unary" variant. This
can be used for explicit type converter to STRING (not for FRAME and
AXIS):
<< <any_type>
For example, such a message or a command can be configured from text lists and
parameters can be inserted (for example a block name):
MSG(STRG_TAB[LOAD_IDX]<<BAUSTEIN_NAME)
