> In your example, there wouldn't be an option of whether you define TS1ST in st.cmd. You lose the default value so you must define it. The problem that I'm trying to solve is that there are literally hundreds of values with facility-specific defaults, not just TS1ST, and of those values most systems only need to define non-default values for a few of them if any.


Use include files with epicsEnvSet!

Example:

1/ FILE WITH DEFAULT VALUES
cat > all_my_default_valules.dft <<EOT
epicsEnvSet(SNOVA_DEVN, "SNOVA" )
epicsEnvSet(SNOVA_FSEP, "_" )
#And a lot more...
EOT

2/ FILE WITH DBLOAD
cat > database_load.dbl <<EOT
dbLoadRecords("${DB_DIR}/snova_asynStream.db","deviceName=${SNOVA_DEVN},_=${SNOVA_FSEP},asynPort=${SNOVAA_PORT},streamProtocol
=${SNOVAA_PROT}");
# And a lot more...
EOT

3/ IOC STARTUP FILE
cat > RunMe <<EOT
#!/usr/bin/env snova-3_14_11

< ${EPICS_IOCHOST}/envPaths                                                  # Path variables
dbLoadDatabase("${DBD_DIR}/snova.dbd")
snova_registerRecordDeviceDriver(pdbbase)

< ${DFT_DIR}/snova.dft
epicsEnvSet(SNOVA_DEVN, "SNOVA_1")                                      # First instance with non default name SNOVA_1
< ${DBL_DIR}/snova_streamEthernet.dbl

< ${DFT_DIR}/snova.dft
epicsEnvSet(SNOVA_DEVN, "SNOVA_2")                                      # Second instance with non default name SNOVA_2
< ${DBL_DIR}/snova_streamEthernet.dbl

iocInit()
EOT

Enjoy!
