Hi I inadvertently stumbled upon this strange 'bug' in my ioc.db file I had the following record: record(subArray, "$(uid):attenuator"){ field(INP, "$(uid):raw") field(NELM, "9") field(MALM, "9") field(INDX, "9") field(FTVL, "LONG") # field(FLNK, "$(dd):getX") } Now the field 'FLNK' is commented out and I have deleted my macro $(dd) in my substitution file. When I run my IOC, I get the following warning macLib: macro dd is undefined (expanding string # field(FLNK, "$(dd)") Warning: 'db/dbExample1.db' line 16
has undefined macros
So the comment (#) still evaluates the macro, even if the documentation says it ignores the whole line. Of course if the macro exist it runs without the warning. Not a critical issue but can be misleading. Thanks Amien |
