Summarized question
I need an environment variable in windows that is auto increment:
setx / a PORT = 1000
and every time you call the% PORT%:
setx / a PORT =% PORT% + 1
The result would be:
echo %PORT%
1001
echo %PORT%
1002
echo %PORT%
1003
Which leads to the question,
Where to put the command?
setx / a PORT =% PORT% + 1
Question Explained
I'm trying to debug an applet in java on windows, other settings did not work, the only one that worked was
create an ambiante variable
JAVA_TOOL_OPTIONS=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=2502
But when doing this only 1 java application can be executed, when trying to run a second an error is thrown saying that the 2502 port is already in use.
My idea now is to do something like
JAVA_TOOL_OPTIONS=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=%PORT%
where %PORT% will be an increased number.
