Hi Mike,
There seems to be a bug in the R3.14.6 sequencer parser when building
under hpux. The problem that we discovered is related to comments and
blank lines found before the state set (ss) is declared. It appears
that if there are more than two lines of continuous comments before the
state set is declared but after the "option" is defined, the compilation
of the sequence fails.

However, problem is a bit more involved because we noticed that the
number of empty lines before or after "option" can also cause the
compliation to fail. For example, if I place 6 blank lines before
"option", the sequence also fails to compile, but 5 blank lines and the
sequence compiles successfully.
The failures currently are only found under the "test" directory. I
talked with Stephanie and she was able to build this same code under
solaris successfully. However, at BESY we are building under hpux.
I've listed only a few examples below of the failed compiles.
- Regards,
  Kristi
Example #1 below fails to compile successfully. If you place the theee
lines of comments before "program" or before "option" or after "ss" the
sequence compiles succssfully.

In example #2 below, if we specify only two lines of comments this
sequence compiles successfully.
program sncopttvar
option +r;
/*

float d; /* Delay variable for managing low state*/
float v; /* Iteration Counter for managing high state*/
ss ss1

****************** EXAMPLE #3 **********************
In example #3 below, if you move the original 3 lines of comments to
within the state set, the sequence also compiles successfully.
program sncopttvar
option +r;

float v; /* Iteration Counter for managing high state*/
ss ss1
