I'm having an interesting little problem with string lists. We have a spell on the mud I play at called 'analyze' which lays out the RIS of a target. I made a trigger to trap that into a string variable...using %replace to turn the spaces into |'s. This made it appear as a string list. But so far I have had utterly no luck adding or deleting anything from lists made this way. Any ideas?

Ugh...correction...it doesn't want to do add/delete to lists with my attacks.

ie: #var attacklist {c 'acid breath'|c fireball|c flamestrike}

What's the trigger or whatever that does the adding/deleting (I'd ask for just the lines that attempt the add and remove, but that might be too incomplete)? I can do this all day long with no problems, so I'm wondering if you have some sort of syntax or other error (such as a case-not-matched error) happening with #ADDITEM or #DELITEM.

This is how it'd look for both commands using the variable quoted above:

#ADDITEM attacklist stuff
#DELITEM attacklist @variable-containing-stuff

you'll note that the stringlist variable does not require the @ character for variables in the above two functions. You can, however, specify a variable in place of stuff and for that you would use the @ character.

Ah, but the problem with mine is that I'm not using text strings to wipe, I'm trying to wipe out record numbers. Because underneath I'm doing a type comparison matched with spells and the like to limit my attacks based on mobs.

Here's the stuff:
=================
view alias:
-----------
#math viewID %1*6
#echo :
#echo : Data record ~#: %1
#echo :-----------------------------.
#echo : Name: %read( 6, @viewID)
#echo : Immunes: %read( 6, @viewID-1)
#echo : Resists: %read( 6, @viewID-2)
#echo : Suscept: %read( 6, @viewID-3)
#echo :-----------------------------'
#var analyze %read( 6, @viewID-1)
#var analyzea %read( 6, @viewID-2)
#var analyzeb %read( 6, @viewID-3)
--------------
Prepare alias:
--------------
#var inita %numwords( @analyze, "|")
#var initb %numwords( @attacktype, "|")
#var attacklist @attack
#while (@inita <> 0) {
#while (@initb <> 0) {
#IF (%item( @analyze, @inita) = %item( @attacktype, @initb)) {#DELITEM attacklist %item( @attacktype, @inintb)}
#math initb @initb-1
}
#math inita @inita-1
}
---------------
Pickup trigger:
---------------
pattern: Immune: (*)
action: #write 6 {%replace( %1, " ", "|")} @record-1
---------------
Variable contents:
---------------
attacktype: acid|energy|none|acid|none|poison|summon|paralysis
attack: c 'acid rain'|c lunar|c spiral|c toxic|c whirlwind|summon asp|summon gnome|c freeze
analyze: fire|cold|electricity|acid|poison|drain
viewID, inita, initb are just number storing variables.

There's the chunk. =P

I can also read and #show out indivitual elements, so I know the database file and lists seem to partially work at least. o.o

It's probably spaces in the item you are trying to add or delete. Most commands, including #VAR, #DELITEM, and #ADDITEM, interpret spaces as the end of a parameter unless they are enclosed in other delimiters.
#var attacklist @attack should be
#var attacklist {@attack}

#IF (%item( @analyze, @inita) = %item( @attacktype, @initb)) {#DELITEM attacklist %item( @attacktype, @inintb)}
should be
#IF (%item( @analyze, @inita) = %item( @attacktype, @initb)) {#DELITEM attacklist {%item( @attacktype, @initb)}}

There may be other statements needing similar corrections.

Hmm, I think I'll try a different route than string lists. I've had some luck using arrays, and considering I haven't done much, it should be easy to adapt. For some reason it's still being fussy about it. Thanks for your time though, I know your advice is gonna come in handy for me down the road. =D
