Populate a waveform from substitutions file

[Dariush Hampai via Tech-talk <tech-talk@aps.anl.gov>]

Hi community,
Hi Mark,

I'm trying to do a SNL state machine, however I need some help in order to conlude the work.
This SNL is really simple: a scan acquisition (from start to and end with step movement), i.e. a motor and a detector. Up to now, I did the while loop and the sequence of commands is right. However, as the motors and the detectors need a waiting time (to reach the position or to wait the end acquisition) I hade to include a nested while loop to wait the "hardware ready". Unfortunately, as all the devices have different way to say "I'm ready", I put a substitution file in order to have the list for all the terminators.
file db/scan.db {
        pattern {ioc, ready}
                {"mm4006_1", "@"}
                {"pi_1", "0"}
                {"pi_2", "1"}
                {"ortec_1", "1"}
                ...
}
Has I define which device I'm using ad a record in db
record(stringout, $(user):motor_device) {
        field(DESC, "Num device motor")
}
so for example
caput xlabsrv2:motor_name mm4006_1
How can I prepare two waveforms (or and array with 2 columns) and populate them as one reads from the substitution file the IOCs, the second the terminatro character,
record(waveform, $(user):ioc) {
        field(DESC, "IOC loaded")
        field(NELM, "200")
        field(FTVL, "STRING")
        field(PINI, "YES")
}
record(waveform, $(user):ready) {
        field(DESC, "Terminators loaded")
        field(NELM, "200")
        field(FTVL, "STRING")
        field(PINI, "YES")
}

find the index that correspond to the IOC selected, and extract the corresponding charater?
Have you any idea?
Thank you in advance

Dariush
