hi All,
How to write a function which will convert string to integer?
please help me…
No reason to write what already exists:
Use this function to evaluate a string representation of a value into its normal representation. The system assigns the result to a variable.
Ok
Data type: boolean
A return code that tells you whether or not an error occurred during the evaluation of the string.
If Ok is… |
It means… |
---|---|
TRUE |
No errors occurred during the evaluation of the string. The system assigned the value to Variable. |
FALSE |
Errors occurred during the evaluation of the string. The system did not modify the original value of Variable. |
If you omit this optional return value and an error occurs during the evaluation of the string, a run-time error occurs. If you include it, the system assumes you will handle any errors.
Variable
Data 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
Data type: text constant or code
A string containing a value of any simple C/AL data type.
Number
Data type: integer
This optional value can be used when exporting data with an XMLport. The only valid value is 9 and this indicates that the data must be converted from XML format to C/SIDE format.
This example shows how the EVALUATE function works when called with three different types of variables.
Value := ‘010196’;
Ok1 := EVALUATE(VarInteger, Value);
Ok2 := EVALUATE(VarDate, Value);
Ok3 := EVALUATE(VarYesNo, Value);
MESSAGE(Text000 + Text001 + Text002,
VarInteger, Ok1, VarDate, Ok2, VarYesNo, Ok3)
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’ |
The message window shows:
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 the system can interpret Value (‘010196’) as both an integer and a date expression, it cannot interpret it as a boolean expression. This causes an error, shown in the return code Ok3 (=FALSE).
