EDCDSECT does the world's ugliest job on assembler ORG and things like FL0 but
it ends up technically correct. Ugly as sin, but the layouts are right.
struct tiot {
unsigned char tiocnjob[8];
/* - JOB NAME */
struct {
struct {
unsigned char _tiocpstn[8];
/* - 8-BYTE PROC STEP NAME FOR PROCS @P1A */
} tiocstpn;
unsigned char _tiocjstn[8];
/* - 8-BYTE JOBSTEP NAME FOR PROCS @P1A */
} tiocstep;

Pascal's WITH statement allowed brief member references without
the requirement for unique names.
