You might need to modify your MANPATH environment variable to include the path to the Perl manpages, but then you should be able to read the documentation with the man command. In addition, Perl comes with its own command, perldoc, which formats the pod documentation and displays it. perldoc is particularly useful for reading module documentation, which might not be installed as manpages; you can also use it for reading the core Perl documentation. The ActiveState Win32 port comes with documentation in HTML format; you can find it in the /docs subdirectory of the distribution.
A $ACCUMULATOR The current value of the write accumulator for format lines. $"literal">$OFMT Contains the output format for printed numbers (deprecated). $? $CHILD_ERROR The status returned by the last pipe close, backtick ('') command, or system operator. $! $OS_ERROR $ERRNO If used in a numeric context, yields the current value of the errno variable, identifying the last system call error. If used in a string context, yields the corresponding system error string. $@ $EVAL_ERROR The Perl syntax error message from the last eval command.
Another type of statement that might be confusing is the evaluation of an array or hash variable as a scalar. For example: $b = @c; When an array variable is evaluated as a scalar, the number of elements in the array is returned. This type of evaluation is useful for finding the number of elements in an array. The special $#array form of an array value returns the index of the last member of the list (one less than the number of elements). If necessary, you can force a scalar context in the middle of a list by using the scalar function.
