I'm working on modifying some commands in our configuration, and had a couple questions.
I've looked online to better understand what the "$" does within these files. For example:
I understand that the command line is referencing a previously established variable (MS_CONFIG_DRIVE) but I don't understand what the $ is doing. Is it telling microstation to look for a previously established variable, named after the $ and between the two parenthesis?
I'm also looking to understand the difference between the ":" and "=" within the config documents.
as well as:
MS_DESIGNMODELSEEDNAME = 2D Design
On the surface, it seems like both operators work in a simlar fashion.
More specifically, I was attempting to set up an if / then statement to reference local files if the network drive was unavailable:
MS_CONFIG_DRIVE = C:/Program Files (x86)/Bentley/MicroStation V8i (SELECTseries)/
%if exists (Y:/)
MS_CONFIG_DRIVE = Y:/
But first I had tried:
MS_CONFIG_DRIVE: C:/Program Files (x86)/Bentley/MicroStation V8i (SELECTseries)/
Then first example worked correctly, but the second one did not. I would appreciate any advice. Our company no longer employees the CAD guru who set up our files, and I am working to better understand how this all fits together.
The sequence is to check if the network is present, then fail over to the local:
%if exists (Y:/) MS_CONFIG_DRIVE = Y:/ %else MS_CONFIG_DRIVE = C:/Program Files (x86)/Bentley/MicroStation V8i (SELECTseries)/ %endif
The $ operator expands the contents of the brackets in the two cases Jan illustrates, it does this only in the context of brackets.

Note that CONNECT Edition configuration is a bit different to V8i, but ultimately easier to work with.
