I can see free space on a VSE volume with Ditto and native VSE tools.
Been like that for as long as I remember.

VSE does not support the Format-? (3? 5?) VTOC record that inventories free
space. "Traditional" DASD space management in VSE involves a chart on the
sysprog's wall showing which tracks of each volume are free. All
"traditional" DASD space allocation in VSE is what z/OS JCL calls ABSTR (is
that the right spelling?). A backstop against "oops" is that VSE datasets
are usually defined with an expiration date (unlike z/OS) which causes VSE
to complain if one attempts to overwrite them.
The more modern approach in VSE uses large VSAM extents as "sub-regions" of
a disk. VSAM then allocates space for sequential datasets within this area.
I think there are also some third-party solutions. I know I set out to write
one once (but did not complete the project).
