.B BASH_COMPAT
The value is used to set the shell's compatibility level.
See the description of the \fBshopt\fB builtin below under
\fBSHELL BUILTIN COMMANDS\fP for a description of the various compatibility
levels and their effects.
The value may be a decimal number (e.g., 4.2) or an integer (e.g., 42)
corresponding to the desired compatibility level.
If \fBBASH_COMPAT\fP is unset or set to the empty string, the compatibility
level is set to the default for the current version.
If \fBBASH_COMPAT\fP is set to a value that is not one of the valid
compatibility levels, the shell prints an error message and sets the
compatibility level to the default for the current version.
The valid compatibility levels correspond to the compatibility options
accepted by the \fBshopt\fP builtin described below (for example,
\fBcompat42\fP means that 4.2 and 42 are valid values).
The current version is also a valid value.
