CSV_READ indicates whether a comma separated value data file should be used by the application as part of initializing a problem and loading data.

The name of the CSV file is the same as the name of the model file base with a .csv extension instead of the .apm extension. When using the Python, MATLAB, or Julia interfaces, the server automatically renames the model and data files to be the same when they are passed to the server. A data file is passed to the server with the csv_load(s,a,’data_file_name.csv’) command. The CSV file can also be removed from the server with the apm(s,a,’clear csv’) command. If there is no CSV (data) file to read and CSV_READ is on, the program continues after leaving a warning message but also turns CSV_READ to 0 (OFF).

CSV_READ indicates whether a comma separated value data file should be used by the application as part of initializing a problem and loading data. The name of the CSV file is the same as the name of the model file. When using the Python, MATLAB, or Julia interfaces, the server automatically renames the model and data files to be the same when they are passed to the server. A data file is passed to the server with the csv_load(s,a,’data_file_name.csv’) command. The CSV file can also be removed from the server with the apm(s,a,’clear csv’) command. If there is no CSV (data) file to read and CSV_READ is on, the program continues after leaving a warning message.
