File Handling Settings in the IDE

Allow 64-bit file access on unknown remote file systems
Specify whether 64-bit file access is permitted for unknown remote file systems. If set to TRUE, the runtime assumes that any unknown remote file system supports 64-bit file access.

Equivalent tunable: remote_64bit_access

Allow programs to use filenames normally reserved for device names
When set to TRUE, the run-time system treats certain predefined names as device-names, so they cannot be used as filenames in your programs. See device_name_detection.

Equivalent tunable: device_name_detection

File name escape character
Specify the escape character used when interpreting filenames provided to the run-time system in calls such as CBL_OPEN_FILE. The escape character is not treated as part of the filename but instead quotes the character immediately following the escape character (such as a space). It is necessary to quote filenames that have embedded spaces within them.

Equivalent tunable: filename_escape_char

File name quote character
Specify the quotation character used when interpreting filenames provided to the run-time system in calls such as CBL_OPEN_FILE. Within a quoted filename, two adjacent quote characters are interpreted as a single quote when deriving the filename. It is necessary to quote filenames that have embedded spaces within them.

Equivalent tunable: filename_quote_char

Lock mode strategy
Specify the locking implementation to be used.

Equivalent tunable: strategy lock_mode

Redirect ASSIGN TO PRINTER to the Windows print spooler
When set to True, redirects WRITE statements to files defined with the ASSIGN TO PRINTER syntax through the Windows print spooler. When set to False, redirects the output directly to the printer port.

Equivalent tunable: printer_redirection

SORT buffer memory allocation
Use default value
Click this to use automatic memory management for SORT and MERGE operations.
Number of bytes of memory to allocate
Specify a minimum number of bytes of memory to allocate for SORT and MERGE operations.
Use External File Mapper
Disabled by default. The External File Mapper allows you to assign values to environment variables in a file. If enabled, the system searches for the file mfextmap.dat.

Equivalent tunable: environment_mapper
