The converter / interpreter will resolve variables. Submit the job with typerun
scan or hold should generate the information you want.
If you're not comfortable with control blocks, IPCS and dumps, then you can use
SDSF to extract the converted JCL albeit a little funky to process.
I can't remember which control blocks you need to run. If you are more skilled,
you could take a dump during the first step and search the storage for the job
card. I would expect a CB eyecatcher which you should be able to find in the
z/OS control blocks manual. From there, you find the pointers in the header.
Keep chasing CB chains until you find one that is usable. Since you want to use
REXX, then find the chain that either originates from PSAAOLD (your ascb) or
PSATOLD (your TCB).
Add a step to the JCL that runs your REXX and have it abend if a dataset is
missing otherwise let it run the job. Realize that IF statements may cause you
problems. You will also want to ignore datasets that are allocated in the job.

Hi Gil,
My intention is to read a Job and make sure that all datasets are available,

What are your constraints? I could envision invoking your REXX with
BPXWUNIX or BPXBATCH and passing your symbols in
//STDPARM DD *,SYMBOLS=JCLONLY
...
