Once more let us clarify exactly what JCL is.
it is Job Control Language.
By itself it does nothing. It is used to invoke the chosen program and to define which datasets are to be used by the DD names associated with the chosen program.
JCL does not have magical powers that solve all problems, JCL is merely the vehicule for telling the processor which program you want it to execute.
You will need to
(a) Write and execute a program
(b) Use your SORT product
(c) Unload, delete the record, reload the VSAM file
