FOR /L

Conditionally perform a command for a range of numbers

syntax   
      FOR /L %%parameter IN (start,step,end) DO command 

key
   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 
                 command-line parameters.

   %%parameter : A replaceable parameter:
                 in a batch file use %%G (on the command line %G)

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

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

Examples

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

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