There seems to be some confusion about these variable names. I
will try to clarify.<br>
<br>
First, As Jeff and Tim correctly point out, variables starting with
the letters END, INC, EQU, and CON are not recommended because these
three letter codes are also keywords that the TRNSYS input file
processor recognizes; it may get confused as to whether it is
processing an equation or a simulation keyword. The situations are
considered to be warnings instead of errors because usually the
input file processor can detect whether there are other letters
following the three letter that would make for a legal variable
name.<br>
<br>
Second, you are correct that the Studio automatically sets up the
variable names for you and that it sometimes uses those same
three-letters codes. However, you can (and probably should) change
the automatic names manually in TRNEdit. The Studio is a jumping-off
point for developing TRNSED applications. You will need to do a
significant amount of modification to your *.trd file in TRNEdit
anyway to make it look the way you want. The rules of syntax are in
the 06-TRNEdit manual.<br>
<br>
Third, the cause of your error is the following pair of lines in
your TRNSED input file:<br>
<br>
<font color="blue" face="Courier New, Courier, monospace">OFOSCILL=5<br>
of oscillations permitted |-|-|0|1|1|99.000|1000<br>
</font><br>
It should be something like:<br>
<br>
<font color="blue" face="Courier New, Courier, monospace">OFOSCILL=5<br>
*|Number of oscillations permitted
|-|-|0|1|1|99.000|1000</font><br>
<br>
The TRNSYS input file processor is trying to parse your equations
and because there is no asterisk at the beginning of the line, the
TRNSYS processor does not recognize it as a comment and instead
tries to read it as an equation.<br>
<br>
Best,<br>

<div>Hi Jeff and David,</div>
<div> </div>
<div><font face="Times New Roman">Thanks for the
advice. But the variable name is from the
components’ parameter, I don’t think I can
change it. Unfortunately, I still can't
locate the fatal error since there is no
equation named OF. And I found it acts very
weird, because sometime it can run the
calculation in TRNED and no error comes up,
and sometime this error comes up, especially
after I linked the required data files under
the same directory.It's kinda random, I have
no clue how to solve this problem. So I turn
to you for more helps. Please check the
attached .trd file and let me know if you
need ! more data file. Thanks very much.</font></div>

You used an illegal variable name. Equation
names cannot start with CON (nor EQU, SIM,
etc.). The TRNSYS processor looks at the
first three letters of any line for key words
and CON is the the beginning of CONstants. So
your variable named CONTROL is thereby
illegal. <br>
<br>
On another note, always look for the first
error in the list file and not the last error
when debugging...<br>
