SET environment variables
First optional parameter:
; parameters are considered parts of a path variable, semicolons are
appended to each element if not already present
-D parameters are properties for Java or Makefile etc., -D will be
prepended and the parameters will be separated by a space
=D the same as above but equal sign is not required
, parameters should be comma separated in the environment variable
- parameters should be separated by the next parameter
Other values mean that the first parameter is missing and the environment
variable will be set to the space separated parameters
Second parameter: name of the environment variable
Next parameters: values
; implies that the equal sign is considered a part of the parameter and is
not interpreted
-D requires parameters in the form name=value. If the equal sign is not found,
the parameters are changed to name=expanded_name
Other options have optional equal sign. If it is found, only the part after
the equal sign will be oprionally expanded.
If the parameter is the minus sign, the next parameter will not be expanded.
If the parameter is a single dot, it will be replaced with the value of the
environment variable as it existed before envset was invoked.
For other parameters the batch looks for the environment variable with the
same name (in uppercase). If it is found, it forms the expanded_name. If
the environment variable with such a name does not exist, the expanded_name
will hold the parameter name without case conversion.
