Description
A fifteen-character string anno can be provided to label parameters and observations in the iTOUGH2 output file. The annotation does not have any function except for making the iTOUGH2 output more readable (exceptions are the user-specified functions; see commands >> USER (p,o). If no annotation is provided, iTOUGH2 internally generates a string which allows unique identification of the parameter or observation, respectively. The internally generated annotation can be used to check the correctness of the iTOUGH2 input.

Example
> PARAMETER
>> van Genuchten's CAPILLARY pressure function
>>> ROCK TYPE : MATRI
>>>> ANNOTATION : AIR ENTRY PRESSURE
>>>> PARAMETER no. : 2
<<<<
>>> ROCK TYPE : FRAC1
>>>> PARAMETER no. : 2
<<<<
<<<
<<
> OBSERVATION
>> CONCENTRATION of COMPONENT No.: 3 in PHASE No.: 2
>>> ELEMENT: ELM10
>>>> NO DATA and no annotation
<<<<
<<<
<<

In the iTOUGH2 output file, the first parameter is referred to as "AIR ENTRY PRESS". The annotation internally generated for the second parameter reads "CAP.PR.2 FRAC1", where "2" indicates that the second parameter of the capillary pressure ("CAP.PR.") function referring to rock type "FRAC1" is estimated. The automatically generated annotation for the observation reads "CONC.(3,2)ELM10".
