If things look like they are working correctly, you can then try mk_vcr. To get a template of the file the mk_vcr will read, execute the following Unix command to copy the example file to your own directory: % cp /ys/gen/data/mk_vcr_example.txt .After you copy the example file, do the following. Insert Side B of the laser optical disk. Then, IDL> mk_vcr,'mk_vcr_example.txt',1,3which execute lines 1 to 3 of the file. (Line 0 puts up a blank frame). If you type IDL> mk_vcr,'mk_vcr_example.txtthe routine will inform you of the number of lines in the file and ask you to enter the start and stop line numbers.
If you want to make a movie, you could try the following IDL program: IDL> sonyloop,8000 ;Get it to a blank frameIDL> for i=0,2 do mk_vcr,'mk_vcr_example.txt',0,23 ;There are 24 lines in the fileIDL> sonyloop,8000 ;End on a blank frameIDL> end As you can see, the sequence in the `for loop' will execute 3 times. Each time through takes about 7 minutes, so the whole movie will be just over 20 minutes in length.
