Evaluates a string representation of a value into its normal
representation. The result is assigned to a variable.

[Ok :=] EVALUATE(Variable, String[, Number])
|
Parameters
- Variable
-
Type: Boolean, integer, option, date, time, text constant, code,
or GUID
Any type of variable. The value of the string is assigned to the
variable
- String
-
Type: Text constant or code
A string containing a value of any simple C/AL data type
- Number
-
Type: Integer
This optional value can be used when exporting data with an
XMLport. The only valid value is 9, which indicates that the data
must be converted from XML format to C/SIDE format.
Property Value/Return Value
Type: Boolean
Specifies whether an error occurred during the evaluation of the
string.
If the return value is true, then no errors occurred
during the evaluation of the string and the value was assigned to
Variable.
If the return value is false, then errors occurred during
the evaluation of the string and the original value of Variable was not modified.
Example
This example shows how to use the EVALUATE function
when called with three different types of variables.
This example requires that you create the following
text constants in the C/AL Globals window.
| Text constant |
ENU value |
|
Text000
|
'VarInteger = #1######, and the return code is: %2\'
|
|
Text001
|
'VarDate = #3######, and the return code is: %4\'
|
|
Text002
|
'VarYesNo = #5######, and the return code is: %6'
|
| |
 Copy Code |
Value := '010196';
Ok1 := EVALUATE(VarInteger, Value);
Ok2 := EVALUATE(VarDate, Value);
Ok3 := EVALUATE(VarYesNo, Value);
MESSAGE(Text000 + Text001 + Text002, VarInteger, Ok1, VarDate, Ok2, VarYesNo, Ok3)
|
The message window displays the following:
VarInteger = 10196 , and the return code is: Yes
VarDate = 01/01/96, and the return code is: Yes
VarYesNo = No , and the return code is: No
This example shows that while Value ('010196') can be
interpreted as both an integer and a date expression, it cannot be
interpreted as a Boolean expression. This causes an error, shown in
the return code Ok3 (=FALSE).
