Consider using StreamDevice. Only the length of EPICS strings is limited
but the length of StreamDevice messages is not (however Eric found a
performance problem if the message is in the order of several
megabytes). StreamDevice can take the values from 8 different (ao)
records and combine them to one long message to the motor controller.

I need to compute a command for a synchronous move of 8 motors.
The final command is possibly a long string (if I split it in 2, it would not be an atomic command!)
I have 7 parameters per motor and one final command line.
How would one program that?
Cascaded gensub is what I would normally do.
But is there a more elegant way?
