Restriction: These tunables are supported for native COBOL only.
acu_library
Loads 'aculibs', the ACUCOBOL-GT compatibility module.
ansi_input_mode
Specifies whether the run-time system uses ANSI or OEM character sets when inputting keystrokes from a console or Application Output window.

Affects the COBOL command line arguments returned from the syntax ACCEPT ... FROM ARGUMENT-NUMBER and ACCEPT ... FROM ARGUMENT-VALUE.
cobconfig_error_report
Specifies whether any errors detected during the processing of the configuration file are reported.
command_line_accept
Specifies whether the first ACCEPT or READ from STDIN takes the input from the command line.
command_line_linkage (deprecated)
Enables you to call a program and pass the command line to the main program as a parameter to be accessed via the Linkage Section.
core_filename
Specifies the name of the file that is generated when the core_on_error tunable is set to 3.
core_on_error
Specifies in what circumstances a core file is produced.
current_day
Specifies the day of the month required to be returned when the ACCEPT identifier FROM DATE syntax or the CURRENT-DATE intrinsic function is used.
current_hour
Specifies the hour of the day that is to be returned when the ACCEPT identifier FROM TIME syntax or the CURRENT-DATE intrinsic function is used.
current_minute
Specifies the minute of the hour that is to be returned when the ACCEPT identifier FROM TIME syntax or the CURRENT-DATE intrinsic function is used.
current_month
Specifies the month of the year required to be returned when the ACCEPT identifier FROM DATE syntax or the CURRENT-DATE intrinsic function is used.
current_second
Specifes the second of the minute that is to be returned when the ACCEPT identifier FROM TIME syntax or the CURRENT-DATE intrinsic function is used.
current_year
Specifies the year required to be returned when the ACCEPT identifier FROM DATE syntax or the CURRENT-DATE intrinsic function is used.
datewarp_dynamic
Specifies whether the day, month, and year values specified by the current_day, current_month, and current_year tunables return static or "rolling" values.
debug_on_error
Specifies whether to enable just-in-time debugging.
debugger_command
Specifies the command to start the debugger when just-in-time debugging is enabled
device_name_detection
Specifies whether programs can use filenames that are normally reserved for device-names.
dynamic_dictionary_limit
Specifies the maximum size of memory to be allocated dynamically at run time for use by virtual heaps.
entry_point_mapper
Specifies whether entry point mapper support is to be enabled.
entry_point_mapper_alias_exists_error
Specifies whether the Entry Point Mapping facility causes a run-time system error COBRT198 ("Load failure") when a program with the same name as an alias definition is found on disk, or whether the aliasing occurs without loading the program with the same name from disk.
entry_point_mapper_search_order
Specifies whether to use entry point mapping to look for programs before or after searching for the programs on disk.
environment_mapper
Specifies whether the External File Mapper is enabled. The External File Mapper allows you to assign values to environment variables in a file. If the External File Mapper is enabled the system searches for the file mfextmap.dat.
error_on_duplicate_entry_point
Controls whether an RTS 119 error is generated when an attempt is made to load a program containing a duplicate entry-point.
filename_escape_char
Specifies the escape character used when interpreting filenames provided to the run-time system in calls such as CBL_OPEN_FILE.
filename_quote_char
Specifies the quotation character used when interpreting filenames provided to the run-time system in calls such as CBL_OPEN_FILE.
intra_process_record_locking
Specifies whether the run-time system can share a file and set record locks against a file within a process.
lock_mode
Selects the locking implementation to be used.
mfpm_access_cancelled_data
Specifies whether the Working-Storage Sections of AMODE programs that have been canceled continue to be addressable.
mfpm_external_data31
Specifies whether external data items are registered with Mainframe Pointer Manager (MFPM) above or below the 16 Mb line.
mfpm_logging
Specifies whether Mainframe Pointer Manager (MFPM) events are to be traced.
no_mfredir
Enables you to reduce the time the run-time system takes to initialize if your project or application does not execute remote programs.
os_error_log
Specifies whether an event is written to the Windows Application Event log whenever run-time system error COBRT199 occurs.
printer_redirection
Redirects WRITE statements through the Windows print spooler.
profile_behavior
Specifies the behavior of the Profiler with regard to the counting of time spent in called programs.
putenv_interface
On certain platforms, this provides backward compatibility with previous products in the setting of environment variables.
reduce_java_signals
Specifies the options that are passed to a JVM when mixing Java and COBOL.
remote_64bit_access
Specifies whether 64-bit file access is permitted for unknown remote file systems.
screen_cols
Specifies the initial width of the Application Output window or console.
screen_lines
Specifies the initial height of the Application Output window or console.
shared_memory_segment_size
Specifies the initial size of the shared memory block allocated by the run-time system.
signal_regime
Specifies whether or not the run-time system is to use its own signal handlers.
strict_file_locking
Enables or disables the strict file locking mechanism for UNIX platforms.
subsystem_cancel_mode
Specifies whether logical or physical cancels are used for CBL_SUBSYSTEM cancels.
timewarp_dynamic
Specifies whether the hours, minutes, and seconds values specified by the current_hour, current_minute, and current_second tunables return static or "rolling" values.
