Does it need to survive an IPL? And does it need to be available cross-system, i.e. within sysplex members? As you admit, there are several other approaches to the general requirement that don't involve a JCL-style symbol. For within an IPL there is the Name/Token pair scheme. Perhaps the simplest that needs no special facilities or authorization is for Program A to write the value into a dataset or UNIX file, and the other jobs to read it from there (or find that it doesn't exist). I do get the impression that you've decided on the solution - quite possibly not the best one - before defining (or at least explaining here) the problem to be solved.
