Changes in this version: 2011-03-04
i_EPIC installation previously put EPIC executables and sample database in folders under "c:\Program Files\i_EPIC\". This caused EPIC run failures on some systems because the user may not have write permission to these folders. So sample database and EPIC versions are now written to a folder called "c:\EPICRuns\". If the user moves these, it is necessary to tell i_EPIC where they are by way of "File" | "Configuration".2011-02-03
Changed EPICRUN.DAT to use 7 digits for run ID if 'output_filename_is_id'=true for versions newer than EPIC3060. Modified epic_output.read_epic_output to skip trying to reading ACM file if output file selection for "2. Annual Cropman (ACM)" is unchecked.2011-01-31
Fixed bug in epic_output_class.read_epic_output that didn't open correct .ACM filename if 'output_filename_is_id'=true.2011-01-26
Fixed bug in epic_controller.write_run_file_3060 that didn't write record ID to epicrun.dat if 'output_filename_is_id'=true.
New fields "Gas Phase O2 Concentration" (CGO2), "Gas Phase CO2 Concentration" (CGCO2), and "Gas Phase N2O Concentration" (CGN2O) in table [Soil Layers].
New fields "Read Directory Option" (ISI0), "ComputeSaturatedConductivity" (ISAT), "ComputeLatitude" (IAZM) and "AutoPApplication" (IPAT) in table [Control Records].2010-03-19
New field "PARM(76)" in table [Parameters].2010-03-11
New field "SOT Import" (XCC) in table [Soils] (used by EPIC to adjust carbon values if the were output of a previous run).2010-02-16
Corrected bugs in epic_output_class.read_output_file_acy that applied to version EPIC0810, reading the far right end (last few variables) of EPIC0001.ACY.2010-01-20
Corrected bugs in epic_controller.write_name_file_1015, EPICSoils.write_epic_input_3060, EPICFertilizer.write, epic_multirun_set.write_epic_mlrn which wrote CR+CR+LF instead of CR+LF to end of line. Added an extra CR+LF to ieweat.dat so that latest EPIC0810 avoids EOF error (UAV0 is written to ieWind.dat). Modified functions for format of PRNT and .ACY file to match latest changes in EPIC0810 source code.2009-12-21
Use TableCheck program to convert existing databases.
Variable "Dynamic Atmospheric CO2" (ICO2) changed from boolean to byte in table [Control Records]. New variable "Carbon Emitted" (FCEM) in table [Fertilizer].
Recent EPIC versions use "PAUSE" command which causes command prompt window loop if run with visible console option off. Added a "stdin" handle that passes a CR-LF-Control+C to EPIC which sometimes avoids this problem. Corrected error in variable order parsed during import for EPICCONT.DAT. Corrected omission of FWLST file during import of EPICRUN.DAT, and fertilizer id during import of field operations. Updated import of fertilizer files.Download i_EPIC with Installer 2011-03-04 (Comes with EPIC5300, EPIC8120, EPIC0250, EPIC3060, EPIC0509 and a 1-record sample compatible with EPIC5300)

Instructions for this download:
This will unzip (you'll need pkunzip or winzip or something similar) to two files, including SETUP.EXE.
Running SETUP.EXE will install the program, by default to c:\Program Files\i_EPIC.
Then you can run the included sample file by selecting "File" | "Open" from the menu and browsing to Sample.MDB in the "Data" Subdirectory (c:\Program Files\i_EPIC\Data).
