| 17 | ! !INTRODUCTION: Package Overview |
---|
| 18 | ! |
---|
| 19 | ! Inpak 90 is a Fortran (77/90) collection of |
---|
| 20 | ! routines/functions for accessing {\em Resource Files} |
---|
| 21 | ! in ASCII format. The package is optimized |
---|
| 22 | ! for minimizing formatted I/O, performing all of its string |
---|
| 23 | ! operations in memory using Fortran intrinsic functions. |
---|
| 24 | ! |
---|
| 25 | ! \subsection{Resource Files} |
---|
| 26 | ! |
---|
| 27 | ! A {\em Resource File} is a text file consisting of variable |
---|
| 28 | ! length lines (records), each possibly starting with a {\em label} |
---|
| 29 | ! (or {\em key}), followed by some data. A simple resource file |
---|
| 30 | ! looks like this: |
---|
| 31 | ! |
---|
| 32 | ! \begin{verbatim} |
---|
| 33 | ! # Lines starting with # are comments which are |
---|
| 34 | ! # ignored during processing. |
---|
| 35 | ! my_file_names: jan87.dat jan88.dat jan89.dat |
---|
| 36 | ! radius_of_the_earth: 6.37E6 # these are comments too |
---|
| 37 | ! constants: 3.1415 25 |
---|
| 38 | ! my_favourite_colors: green blue 022 # text & number are OK |
---|
| 39 | ! \end{verbatim} |
---|
| 40 | ! |
---|
| 41 | ! In this example, {\tt my\_file\_names:} and {\tt constants:} |
---|
| 42 | ! are labels, while {\tt jan87.dat, jan88.dat} and {\tt jan89.dat} are |
---|
| 43 | ! data associated with label {\tt my\_file\_names:}. |
---|
| 44 | ! Resource files can also contain simple tables of the form, |
---|
| 45 | ! |
---|
| 46 | ! \begin{verbatim} |
---|
| 47 | ! my_table_name:: |
---|
| 48 | ! 1000 3000 263.0 |
---|
| 49 | ! 925 3000 263.0 |
---|
| 50 | ! 850 3000 263.0 |
---|
| 51 | ! 700 3000 269.0 |
---|
| 52 | ! 500 3000 287.0 |
---|
| 53 | ! 400 3000 295.8 |
---|
| 54 | ! 300 3000 295.8 |
---|
| 55 | ! :: |
---|
| 56 | ! \end{verbatim} |
---|
| 57 | ! |
---|
| 58 | ! Resource files are random access, the particular order of the |
---|
| 59 | ! records are not important (except between ::s in a table definition). |
---|
| 60 | ! |
---|
| 61 | ! \subsection{A Quick Stroll} |
---|
| 62 | ! |
---|
| 63 | ! The first step is to load the ASCII resource (rc) file into |
---|
| 64 | ! memory\footnote{See next section for a complete description |
---|
| 65 | ! of parameters for each routine/function}: |
---|
| 66 | ! |
---|
| 67 | ! \begin{verbatim} |
---|
| 68 | ! call i90_LoadF ( 'my_file.rc', iret ) |
---|
| 69 | ! \end{verbatim} |
---|
| 70 | ! |
---|
| 71 | ! The next step is to select the label (record) of interest, say |
---|
| 72 | ! |
---|
| 73 | ! \begin{verbatim} |
---|
| 74 | ! call i90_label ( 'constants:', iret ) |
---|
| 75 | ! \end{verbatim} |
---|
| 76 | ! |
---|
| 77 | ! The 2 constants above can be retrieved with the following code |
---|
| 78 | ! fragment: |
---|
| 79 | ! \begin{verbatim} |
---|
| 80 | ! real r |
---|
| 81 | ! integer i |
---|
| 82 | ! call i90_label ( 'constants:', iret ) |
---|
| 83 | ! r = i90_gfloat(iret) ! results in r = 3.1415 |
---|
| 84 | ! i = i90_gint(iret) ! results in i = 25 |
---|
| 85 | ! \end{verbatim} |
---|
| 86 | ! |
---|
| 87 | ! The file names above can be retrieved with the following |
---|
| 88 | ! code fragment: |
---|
| 89 | ! \begin{verbatim} |
---|
| 90 | ! character*20 fn1, fn2, fn3 |
---|
| 91 | ! integer iret |
---|
| 92 | ! call i90_label ( 'my_file_names:', iret ) |
---|
| 93 | ! call i90_Gtoken ( fn1, iret ) ! ==> fn1 = 'jan87.dat' |
---|
| 94 | ! call i90_Gtoken ( fn2, iret ) ! ==> fn1 = 'jan88.dat' |
---|
| 95 | ! call i90_Gtoken ( fn3, iret ) ! ==> fn1 = 'jan89.dat' |
---|
| 96 | ! \end{verbatim} |
---|
| 97 | ! |
---|
| 98 | ! To access the table above, the user first must use {\tt i90\_label()} to |
---|
| 99 | ! locate the beginning of the table, e.g., |
---|
| 100 | ! |
---|
| 101 | ! \begin{verbatim} |
---|
| 102 | ! call i90_label ( 'my_table_name::', iret ) |
---|
| 103 | ! \end{verbatim} |
---|
| 104 | ! |
---|
| 105 | ! Subsequently, {\tt i90\_gline()} can be used to gain access to each |
---|
| 106 | ! row of the table. Here is a code fragment to read the above |
---|
| 107 | ! table (7 rows, 3 columns): |
---|
| 108 | ! |
---|
| 109 | ! \begin{verbatim} |
---|
| 110 | ! real table(7,3) |
---|
| 111 | ! character*20 word |
---|
| 112 | ! integer iret |
---|
| 113 | ! call i90_label ( 'my_table_name::', iret ) |
---|
| 114 | ! do i = 1, 7 |
---|
| 115 | ! call i90_gline ( iret ) |
---|
| 116 | ! do j = 1, 3 |
---|
| 117 | ! table(i,j) = i90_gfloat ( iret ) |
---|
| 118 | ! end do |
---|
| 119 | ! end do |
---|
| 120 | ! \end{verbatim} |

---|
| 161 | ! \subsection{Package History} |
---|
| 162 | ! Back in the 70s Eli Isaacson wrote IOPACK in Fortran |
---|
| 163 | ! 66. In June of 1987 I wrote Inpak77 using |
---|
| 164 | ! Fortran 77 string functions; Inpak 77 is a vastly |
---|
| 165 | ! simplified IOPACK, but has its own goodies not found in |
---|
| 166 | ! IOPACK. Inpak 90 removes some obsolete functionality in |
---|
| 167 | ! Inpak77, and parses the whole resource file in memory for |
---|
| 168 | ! performance. Despite its name, Inpak 90 compiles fine |
---|
| 169 | ! under any modern Fortran 77 compiler. |
---|
| 170 | ! |
---|
| 171 | ! \subsection{Bugs} |
---|
| 172 | ! Inpak 90 is not very gracious with error messages. |
---|
| 173 | ! The interactive functionality of Inpak77 has not been implemented. |
---|
| 174 | ! The comment character \# cannot be escaped. |
---|
| 175 | ! |

| 200 | ! !REVISION HISTORY: |
---|
| 201 | ! 03Jul96 - J. Guo - evolved to Fortran 90 module. The |
---|
| 202 | ! modifications include 1) additional subroutines to |
---|
| 203 | ! dynamically manage the memory, 2) privatized most |
---|
| 204 | ! entries, 3) included "i90.h" into the module source |
---|
| 205 | ! with better initializations, 4) removed blockdata, 5) |
---|
| 206 | ! used a portable opntext() call to avoid I/O portability |
---|
| 207 | ! problems. |
---|
| 208 | ! |
---|
| 209 | ! See I90_page() I90_Release(), and I90_LoadF() for |
---|
| 210 | ! details. |
---|
| 211 | ! |
---|
| 212 | ! 05Aug98 - Jing Guo - |
---|
| 213 | ! Removed i90_page() and its references. |
---|
| 214 | ! Added internal subroutines push_() and pop_(). |
---|
| 215 | ! Modified i90_release(). |
---|
| 216 | ! Added i90_fullrelease(). |
---|
| 217 | ! Removed %loaded. Check i90_depth instead. |
---|
| 218 | ! 06Aug98 - Todling - made I90_gstr public |
---|
| 219 | ! 20Dec98 - Jing Guo - replaced the description of I90_Gstr |
---|
| 220 | ! 28Sep99 - Jing Guo - Merged with the MPI version with |
---|
| 221 | ! some addtional changes based on |
---|
| 222 | ! merging decisions. |
---|
| 223 | ! 12Oct99 - Larson/Guo - Overloaded fltget() to new routines |
---|
| 224 | ! getfltsp() and fltgetdp(), providing better support |
---|
| 225 | ! for 32 and 64 bit platforms, respectively. |

---|
| 824 | ! in Inpak 77 by Jing Guo. A table is a construct like this: |
---|
| 825 | ! |
---|
| 826 | ! \begin{verbatim} |
---|
| 827 | ! my_table_name:: |
---|

---|
| 835 | ! :: |
---|
| 836 | ! \end{verbatim} |
---|
| 837 | ! |
---|
| 838 | ! To access this table, the user first must use {\tt i90\_label()} to |
---|
| 839 | ! locate the beginning of the table, e.g., |
---|
| 840 | ! |
---|
| 841 | ! \begin{verbatim} |
---|
| 842 | ! call i90_label ( 'my_table_name::', iret ) |
---|
| 843 | ! \end{verbatim} |
---|
| 844 | ! |
---|
| 845 | ! Subsequently, {\tt i90\_gline()} can be used to gain acess to each |
---|
| 846 | ! row of the table. Here is a code fragment to read the above |
---|
| 847 | ! table (7 rows, 3 columns): |
---|
| 848 | ! |
---|
