To answer my own question ...

short enable[50];
assign enable to "";                 /* default value for the whole array */
monitor enable;

/* Later in ss */
    state initState {
        entry {
        }
        when (pvConnectCount() == pvChannelCount()) {   /* check docs for pvAssignCount() in section 2.14 */
            seqLog("All static channels connected\n");
            seqLog("Connecting dynamic channels ...\n");
            for(i=0;i<50;i++) {
                sprintf(pvName, "%s:PowerSply:EnblBO", p_magnets[i]);
                pvAssign(enable[i], pvName);
            }
        } state idleState
        exit {
        }
    }


FYI

Subject: SEQ with dynamic assignment of PV in array variable
Date: Mon, 3 Jun 2013 10:28:52 -0700

Hello,

I am working on a seq program.
For that program, I am interacting with magnet power supplies.
The interfaces to the power supplies are all the same (about 10 PV each).

For each interface PV, I would like do to something like this...

#define NB_OF_SUPPLIES  50
short enable[NB_OF_SUPPLIES];
assign enable[0] to "I:S001:PS:EnableBO";
assign enable[1] to "I:SO10:PS:EnableBO";
...
monitor enable;

but programmatically.

I looked at the docs and they are somewhat confusing.

Q: Is there a place to put the pvAssign statement?
Q: Should the array's cell be initialized/assigned to ""  during declaration?
Q: Can I monitor a not-yet configured PV array?
Q: How can I find out about the connection to each of the PVs?
etc.

If anyone has an example of using pvAssign on array variables (i.e. enable),  I would appreciate it.

Regards,
--
Emmanuel
