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.
