Expression Positions in Release 7.0, EhP2
1. Using functions and expressions
3. Predefined 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 enhanced considerably in Release 7.0, EhP2:
- Calculation expressions, predefined functions, and functional methods can be used in general expression positions.
- Numerical expressions can be used in numerical 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 logical 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 of the statement COMPUTE were the only general expression positions.
Note
The character-like arguments of description functions are, with one exception, character-like expression positions as of EhP1. Before EhP1, they were 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
Predefined functions with multiple arguments
Release 7.0, EhP2 introduces new predefined functions that can now accept multiple arguments. A predefined 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:
- Rounding functions
- Search, similarity, and processing functions for character strings
-
Logical functions
