Hi Andrew
Thanks for the reply, that was what I thought. But just to clarify my
specific case. I'm using StreamDevice2 and have a INP field as follows with
template/substitution.
field(INP, "@TEST.protocol getCs($(DEVICE),C2,C3,C4) $(port) 0")
If I understand things correctly, whatever the length of DEVICE and port I
shouldn't encounter problems. Well due to the length of the field at least.
Regards
Steve

Is there any length restriction on an INP field, before or after the
expansion of any macros it may contain?
Unlike many places inside the IOC, there is no built-in length limitation
to
the value that can be placed in a link field using dbLoadRecords(), which
means that the @parm part of a hardware link address can be as long as you
like.
Of course if you want to read or update the field through CA there is a 40
character limit to the string you can pass as a DBR_STRING, and with the
new
array-of-chars support in 3.14.11 using the @ field modifier I believe CA
will
still limit you to passing at most 72 characters to/from a link field.
