Expression Positions in Release 7.0, EhP2
1. Using functions and expressions
3. Access to components of structured return values
4. Built-in functions with multiple arguments
Other versions: 7.31 | 7.40 | 7.54
Note
The program DEMO_EXPRESSIONS shows examples of the enhanced expressions in Release 7.0, EhP2.
Modification 1
Using Functions and Calculation Expressions
The usability of functions and expressions in operand positions has been substantially improved in Release 7.0, EhP2:
- Calculation expressions, built-in functions, and functional methods can be used in general expression positions.
- Numeric expressions can be used in numeric expression positions.
- String expressions can be used in character-like expression positions.
-
Functional methods can be used in functional operand positions.
From Release 7.0, EhP2, the following general expression positions are available:
-
Operands of relational expressions
Example:a + b < oref->meth( ) -
Actual parameters for input parameters of methods
Example:oref1->meth1( oref2->meth2( ... ) )
Before Release 7.0, EhP2, operand positions on the right side of assignments with = were the only general expression positions.
Note
From EhP1, the character-like arguments of description functions are (with one exception) character-like expression positions. Before EhP1, they were character-like functional operand positions.
Modification 2
Method Chainings
As well as the previous chained names, operand positions that accept functional methods now also accept method chainings, that is chained method calls and chained attributes accesses.
Modification 3
Access to Components of Structured Return Values
If the result of a functional method or method chaining is structured, the call can (like the name of a structure) be written directly in front of the structure component selector to access a component of the result.
Modification 4
Built In Functions with Multiple Arguments
Release 7.0, EhP2 introduces new built-in functions that can now accept multiple arguments. A built-in function of this type is called in the same way as a functional method with multiple input parameters.
... func( p1 = arg1 p2 = arg2 ... ) ...
The new functions are include:
- Rounding functions
- Search, similarity, and processing functions for character strings
-
Logical functions
