Formatted Input
scanf
This SSI function reads a string passed from an object in a HTML form, interprets
the string according to the specification in format, and stores the result in the Out-
put (OUT) area according to the passed arguments. The formatting of the string is
equal to the standard C function call scanf().
Syntax:
<?--#exec cmd_argument=’scanf(ObjName, format,
Arg1,..., ArgN), ErrVal1,..., ErrvalN’
-->
ObjName
The name of the object with the passed data string
format
Specifies how the passed string shall be formatted
Arg
