Tests if a character string contains only digits.
$isdigit(string)| string | a character string or an expression that evaluates to a character string |
1-character binary string. Evaluates to 1 ($True) if string meets the validation test; otherwise, evaluates to 0 ($False).
This function tests if a particular character string is all digits.
$isdigit("0123")Evaluates to $True.
$isdigit(2.3)
Evaluates to $False.
Obtain the name of the current event.
$ObjEventName
Returns a string.
COM objects are being discontinued by Microsoft and may not be available in future releases of Zim-X.
The name of the database as provided in the connection.
$dbname
A character string. Cannot be reset by an application program.
The $DBName function is set to the value of the database name provided as a connection parameter.
The file system path for the Zim Server Access Modules (SAM).
$sqlpath
The pathname of the directory pointed to by the SQLCPI variable.
The SQLCPI variable is defined in the registry. The SQLCPI variable indicates the directory containing the Zim Server Access Modules.
The field number of the current form field.
$fieldnum
A number. ZIM sets the $FieldNum to the field number (FNum) of the form field in which the cursor is located when FORM INPUT terminates.
The combination of $FormNum, $Subscript and $FieldNum can uniquely identify a particular form field in a Zim display.
The current instance of the current form
$subscript n
| n | Any numeric value between 1 and 8 |
In combination of $FormNum, $subscript, $ FieldNum can uniquely identify a particular for field in a Zim display.
form set (reverse) ($ formnum,$ fieldnum,$subscript)
Sets the current instance of a repeated form to reverse video.
find Products where ProdCode = fProducts.ProdCode [$subscript]
Finds all product records that match the product code on the current instance of the repeated form fProducts.
Returns a cryptographic 128-bit hash value.
$md5(expression)
| expression | an expression that evaluates to a string |
The value returned by $MD5 is a hexadecimal 32-characters long string representing the cryptographic hash value of the expression used as the argument.
out $md5(1)
45954632C04A953592D33FDC5F59A64C
out $md5("1")C4CA4238A0B923820DCC509A6F75849B
The returned values are different because the $md5(1) first converts the number 1 to a character string (which becomes ” 1″) and then applies the MD5 algorithm to it.
Provides the failure error code returned by a component function.
$ObjErrCode
Number (LONGINT). Can be reset by an application program.
The variable gives the failure error code returned by a component function. This variable is set to $null when a component operation triggers a Zim error and is set to a meaningful value when a Zim 5207 error is encountered.
COM objects are being discontinued by Microsoft and may not be available in future releases of Zim-X.
Destroy an ActiveX object.
$ObjDestroy (Object)
| Object | a component object variable or formfield of type OLE |
Returns a boolean; TRUE if the object was destroyed.
In Zim 7.1, setting an object to $Null will also destroy it. This is the preferred method of releasing an object. For example:
Let MyObj = $Null
Instead of
$ ObjDestroy(MyObj)
COM objects are being discontinued by Microsoft and may not be available in future releases of Zim-X.
Provides the name of the ActiveX object that triggered an exception.
$ObjErrObjectType
Character string (VARALPHA). Can be reset by an application program.
The variable gives the name of the ActiveX object that triggered an exception in the component. This variable is set to $null when a component operation triggers a Zim error but is set to a meaningful value when a Zim 5207 error is generated.
COM objects are being discontinued by Microsoft and may not be available in future releases of Zim-X.
