A question regarding MSI (Macro Substitution and Include) tool:

Is there a way to set the value of a macro in the substitutions file
for later use without triggering an immediate substitution?

Any tips for doing something like this with the existing tool?

global { SEX=Male }
file xxx.template {
       pattern {FNAME, LNAME}
       {John, Smith}
       {George, Jones}
       {James, Taylor}
       {Robert, Redford}
       {Larry, Cableguy}

global { SEX=Female }
file xxx.template {
       pattern {FNAME, LNAME}
       {Susan, Williams}
       {Judy, Johnson}
       {Melinda, Martin}
       {Cathy, Lewis}
       {Linda, Hall}
    }

To explain a bit more, there have been a number of improvements made to
the msi program as part of importing it back into Base 3.15. There is
now a formal EBNF syntax definition for the substitutions file, and we
support global macros and optionally respect standard scoping rules. The
3.14 IOC (dbLoadTemplate command) does not understand the new keywords,
but the 3.15 IOC (currently still in development) does.

I am sorry.

I am using the Debian packaged version of EPICS Base 3.14, and Michael

has backported the 3.15 msi into 3.14 as part of that packaging effort.

It's easy to forget about such stuff when things just work (TM).
