(subtitle "Dynamic system symbols") in Chapter 2: The system determines the substitution text for dynamic system symbols when the ASASYMBM or ASASYMBF service is called to do the substitution. For example: • For system symbols within a parmlib member, when the parmlib member is processed. • For system symbols within JCL, when the JCL undergoes conversion. • When an application program is running. -- Dale R.
