let int# = ADDITEM ( list , "item", int_separator )
let int# = ADDUNIQ ( list , "item", int_separator )
let str# = ADDITEM ( "list", "item", int_separator )
let str# = ADDUNIQ ( "list", "item", int_separator )

ADDITEM () add an item to a list.
ADDUNIQUE () add an item to a list only if it is not already in the list.

let str# = SORT ( "list" , "key" , int_separator )
let int# = SORT ( io_strvar , "key" , int_separator )
SORT() sorts a list alphabetically or numerically.

let str# = DIRLIST ( "directory" , "pattern" , "mask", separator, ecode )
DIRLIST() generates a list from a directories entries.

let str# = NEXTITEM ( index_column , "source", 'seper_char' ) def ','.
let str# = NEXTFIELD ( field_column , "source", 'seper_char' ) def ':'.
let str# = NEXTLINE ( line_column , "source", 'seper_char' ) def '\n'.
NEXITEM() and friends sequentially read a list one item at a time.

let str# = UNIQUE ( "list" , [ int_separator ] )
UNIQUE() ensure there are no duplicate items in a list.

let str# = STRCAT ( "stra", %strb% , 'strc' , ... )
STRCAT() concatenates several strings.

let str# = GETCWD ( )
GETCWD() returns the current working directory.

Changes
-------
Warning : these may effect existing macros.

STRTIME(),NOW() now returns 1970.01.01 when time is un-available.
FCOPY(),FSIZE() return -3 for size too big for integer.
REWIND(),FSEEK(),FLOCK() now use 0 and -1 as return values.

22-012 : alarm .flags being set to cached when not shared.
22-013 : stringexpr() LOGGER call was not using -> s.
22-014 : Default open dir mask changed to "All".
22-015 : Invalid or unavalable time is 0, rather than -1.
22-016 : Shared mem still deadlocks after crash.
22-017 : %alarms.shared% was incorrect. So was %alarms.cached%.
22-018 : FIND/LOC <NUL> inconsistent. F<NUL> now stops on empty line.
22-019 FCOPY () should use OPENED_FMODE for new files mode.
22-020 FCOPY () should return -3 for file size too big for return value.
22-021 FSIZE () should return -3 for file size too big for return value.
22-022 REWIND () should use -1/0 return value. Documentation wrong.
22-023 FSEEK () should use -1/0 return value.
22-024 FLOCK () should use -1/0 return value. flocknedfile () issue.
22-025 H Xn shrinks the history list.
22-026 menu Modes/Screen_return exits session.
22-027 STRCAT() clears target string.
22-029 Need an optional separator for MENU().

Open bugs
---------

22-018 WHICH double reports on "*" and same directory in PATH.
22-015 Shared mem still splits to different segments after crash.
22-028 errpro () Help file from syntax error not showing. Timer is huge.
When mode SHORTER with other combination.
22-030 let int# = "^J" is accepted as decimal 30.
22-031 winpick() needs an optional "title" for MENU().

Discussion :
If Open/ed crashes and is restarted, it may start a new shared memory segment for alarms.
The only way around this is to exit all of your Open/ed sessions and
remove the control file : %alarms.control.file%.

The WHICH command examines each directory in PATH.
If '*' is specified and the same directory is also specified, then the
WHICH command will double report if the command is found.

The integer value of a control character is ^X.
Quoted control codes needs a review.
