One way to do conditional execution in an EPICS database is by using the SELM and SELN fields of a seq record.  Set SELM to "Specified", and write a number to the SELN field. If you want more than one of several things to happen, you can write "Mask" to SELM, and write a bitmap value to SELN, specifying which things to do.

+1
The combination of a calcout record (evaluating conditions) writing to a seq record in "Mask" mode (executing actions) is extremely powerful. As actions can include delays and changing the calcout's fields, that setup is good enough for a small state machine. (You will also win any district level obfuscation contest.)
