How hard is it to delete lots of data sets? – Easy!

I was configuring a product and had some problems, so I needed to clean up.  I had hundreds of VSAM clusters.  I started using ISPF 3.4 and using the delete line command, but you have extra typing to do for VSAM files, so I gave up.

I had a faint memory of using a MASK to delete things, and a quick search gave me

//S1 EXEC PGM=IDCAMS 
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
DELETE COLIN.O.RTE.RK* MASK
/*

Which deleted all my data sets.

Wasn’t this easy!
