ircII help - assign

Usage: ASSIGN [[-]<user-variable> []]

  ASSIGN lets you create user variables which are automatically   expanded by ircII in aliases using the $variable-name format.   For example, if you had defined:     assign me The Big Cheese   Then, in an alias, $me would expand to "The Big Cheese". These   are straight textual substitutions. You can use these kind   of variables as counters and indexes into lists as well. For   example:     assign index 0     assign index ${index+1}   The first line sets "index" to 0, the seconds increments index by 1.   Note that the second will always be expanded if used in another   alias (where $ are normally expanded). If you want it to be   expanded if typed at the input line, you must first   set/input_aliases to ON.

  Note: In the above example, the mathematical expression must be   enclosed by {}'s otherwise the + would be treated as an alias   delimiter and the addition not performed. (See @ as well)

  Suppose now you wanted to use index to get a single word in a list,   you could do:     alias WORD echo $($index)   Then doing:     WORD This is a test   would display the index'th word in the list.   The $($index) format does the following: it parses the text   between the () as a sub-alias. The "$index" is thus evaluated   and returns its value. This value is then replaced for the ()   expression and evaluated. So, if you had:     assign index 1   Then, the following would be evaluated:     $index becomes 1 which given     $(1) which becomes simply $1   Thus the $1 argument is used.   This functionality can be nested. This the following:     assign A Hey You!     assign B A     assign C B     alias NESTING echo $($($C))   will cause NESTING to display "Hey You!"

  The following format are also legal:     $#name evaluates to the number of words in name     $@name evaluates to the number of characters in name   You can use these with the mathematical expressions as well,   for example:     assign foo Testing One Two     echo $#foo $@foo     assign junk ${#foo + @foo}   The echo line will display 3 15 and the variable junk have the   value 18.

  Additionally, values assigned wit SET FUNCTION_RETURN are   taken to be the return value of a function.

IMPORTANT NOTE:   There is a special version of this command called '@'   for use in aliases and scripts. It is well suited to mathematical   operations. Its use over ASSIGN is highly recommended.
