> Hi Tony,
> 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! -- Emmanuel |
