Use TQOPNT to open a transparent thermochemical data-file for reading by ChemApp.
Added for ChemApp version 4.0.0
|Name||Type|| Value set on call or returned
|NAME||CHARACTER|| Set to the filename of the transparent data-file to open
|UNIT||CHARACTER|| Set to the unit number under which it should be opened
|NOERR||INTEGER|| Returns an error number
Use TQOPNT to open a thermochemical data-file in transparent format for reading.
The unit number under which the data-file needs to be opened should normally be determined in advance using a call to TQGIO with the option 'FILE'.
A file that has been opened using TQOPNT should subsequently be closed only with TQCLOS.
FORTRAN programmers may use the standard
OPEN statement instead of
TQOPNT, if ChemApp is used as a static library. This is not
recommended though, because the specifiers needed in calls to
when opening transparent data-files are compiler-dependent.
TQOPNT cannot be used to open ASCII or binary thermochemical data-files. For this purpose, use TQOPNA/TQOPNB instead.
Please see also chapter 1.11 for details and differences of thermochemical data-files formats.
