I want to have variables in the string that %expandlist expands, but expandlist wants to evaluate them before outputting them... if there is a way to inhibit the expansion of a string that would be great to know.

EXAMPLE1
how do you get around this:
#VAR stringlist {}
#ADDITEM stringlist "@"
#ADDITEM stringlist "bob"
#ALIAS aliastest {<%expandlist(@stringlist,"")>}

---------------------------------------
output
#ALIAS aliaslist {@|bob}

it puts in a pipe symbol.

EXAMPLE2
#var stringlist = "#IF (@bob = 0) {kill bob}"
#ALIAS aliastest {<%expandlist(@stringlist,"")>}
---------------------------
output
#ALIAS aliastest {#IF (0 = 0) {kill bob}}

----------------------------

any suggestions?

any alternative structures that can get this same effect?
the example in ex 2. is closest to what I'm trying to do.

I think maybe you should start with a description of what you want to do, or what you are trying to do. You have described how your trying to do something. Obviously that HOW isn't working, but if we understood what that SOMETHING was we could suggest another way.

this is what I want to do:
list = "a|b|c"
#ALIAS newalias {<%expandlist(@list,"")>}
and have the result be:
#ALIAS newalias {abc}

where a, b, c potentially contain variables or lists of commands...

such as:
list = "#IF (@class = syssin) {hypnotise @tar}|; |#IF (@balance = 1) {seal @tar 10}"

obviously this wont work, because expandlist evalutates the variables during expansion, but, im suprised that it puts a pipe in (see EX1) even when the expansion character is a "". I was trying to fool expandlist by putting @ in as a seperate list element.

What you are looking for is controlled expansion.

#EXEC {%concat("#ALIAS newalias {",%replace(%expand(@list,1),"|",""),"}")}

Hi,

You could do the following:

#FUNC list "#IF (@class = syssin) {hypnotise @tar}|#IF (@balance = 1) {seal @tar 10}"
#ALIAS newalias {<%expandlist(@list,";")>}

I guess the output is what you expect;-)

scudfly your #FU should be a #VAR I believe... and the output would have similar problems as those I discussed.
------------------

ahhhh yes Vijilante that is perfect... can you explain why the %expand is inside of the replace? it would seem that this would be the same as:
#EXEC {%concat("#ALIAS newalias {", %replace(@list,"|",""), "}")}
because the %expand version of list would be input into the replace command...

No, #FUNC is a function.
It exports as #var for some unknown reason.
Think of func as a var with code.

#FUNC is not like #VAR, it will NOT expand variables,
so the output is correct.
I've wrote some useful script with the help of #FUNC for years,
you could just try and see the output.

Slight Derail ahead

#FUNC name {code here} is the same as #VAR name "code here" but not the same as #VAR name {code here}, the differance has to do with the use of "" (to not expand/evaluate on creation) and {} (to expand on creation}

A function is just a variable that is not expanded when it is created. The problem with exporting scripts with funcs is that they get exported as #VAR name {code here} instead of #VAR name "code here" and when they are imported they get expanded.
