Conditionally perform a command for a range of numbers.


   start       : The first number  
   step        : The amount by which to increment the sequence 
   end         : The last number 

   command     : The command to carry out, including any parameters.
                 This can be a single command, or if you enclose it
                 in (brackets), several commands, one per line.

   %%parameter : A replaceable parameter:

So (20,-5,10) would generate the sequence (20 15 10)

(1,1,5) would generate the sequence 1 2 3 4 5

The numbers must all be within the range of 32 bit signed integer numbers (-2,147,483,648 through 2,147,483,647)


If the start,step,end are left null or (0) then the command will loop indefinitely, Ctrl-C will abort the whole script.

FOR is an internal command.


Count from 1 up to 5

FOR /L %%G IN (1,1,5) DO echo %%G

Non-numeric lists can use a standard FOR command:

FOR %%G IN (Sun Mon Tue Wed Thur Fri Sat) DO echo %%G
