dos

Have done quite a bit of searching for a guide (of any substance) for the above to no avail. Can anyone refer me to one?

In the present tense however, I am trying to understand the below code example, which returns a two digit representation of the month, that corresponds to the 3 character month name set in v:

    SET v=May

    SET map=Jan-01;Feb-02;Mar-03;Apr-04;May-05;Jun-06;Jul-07;Aug-08;Sep-09;Oct-10;Nov-11;Dec-12
    CALL SET v=%%map:*%v%-=%%
    SET v=%v:;=&rem.%

    ECHO.%v%
