Yes, I know writeini will work. It's the $read that I thought was a problem with larger files... though I admit I've never tried as I don't need ini files that are that large.

replied to you only becuase yours was the last item mentioning /hsave -i
I think everyone should just forget the -i option, try doing a tick test on saving the file with -i compared to without it, I tried on a 10,000 item table, and OMG but does it take a long time. While a 10,000 item /HSAVE hash_table temp.txt took 16 or 32 ticks (ie: an unacuratly small time).

Yeah, I did notice it took a little time for even that 107k test file. I guess it's really a matter of what is faster (probably his current while loop method), and whether or not he wants to consider changing how he's handling/storing the data so that it may work without dealing with this problem.

ok here ya go try this out.... ;Usage hdel.wilddata -bN <name> <matchtext>
;
; Deletes hashtable Items who's data matches the matchtext given.
;
; -bN : N being a number 1 or greater (default 10),
; N represents the point where a simple loop is no longer used to remove matched data items
; ie: if N is 5 and there are only 3 data matched items then a simple loop is used
; if N is 10 and there are 15 data matched items then the hsave/filter method is used.
;
alias hdel.wilddata {
;
; Pharse command line phase
;
var %breakpoint = 10
if (-* !iswm $1) {
var %hdel.wilddata.hashtable = $1
var %hdel.wilddata.matchtext = $2-
}
else {
if ($calc($mid($1,$calc($poscs($1,b) + 1))) isnum 1-) { var %breakpoint = $v1 }
var %hdel.wilddata.hashtable = $2
var %hdel.wilddata.matchtext = $3-
}
;
; Do the hdel phase
;
if (((%hdel.wilddata.hashtable != $null) && (%hdel.wilddata.matchtext != $null)) && ($hfind(%hdel.wilddata.hashtable,%hdel.wilddata.matchtext,0,w).data)) {
if ($v1 > 0) {
if ($v1 == $hget(%hdel.wilddata.hashtable,0).item) {
;
; Matchtext matched entire table
;
hdel -w %hdel.wilddata.hashtable *
}
elseif ($v1 < %breakpoint) {
;
; Simple loop method
;
while ($hfind(%hdel.wilddata.hashtable,%hdel.wilddata.matchtext,1,w).data) { hdel %hdel.wilddata.hashtable $v1 }
}
else {
;
; Hsave/filter method
;
set %hdel.wilddata.hashtable %hdel.wilddata.hashtable
hsave -ou %hdel.wilddata.hashtable hdel.wilddata.tempfile.txt
window -hn @hdel.wilddata.hidden.window
loadbuf -r @hdel.wilddata.hidden.window hdel.wilddata.tempfile.txt
hsave -oun %hdel.wilddata.hashtable hdel.wilddata.tempfile.txt
filter -fkn hdel.wilddata.tempfile.txt hdel.wilddata.filter.alias %hdel.wilddata.matchtext
window -c @hdel.wilddata.hidden.window
unset %hdel.wilddata.hashtable
}
}
}
}
alias -l hdel.wilddata.filter.alias { hdel %hdel.wilddata.hashtable $line(@hdel.wilddata.hidden.window,$calc(-1 + 2 * $1)) }it uses 3 possable methods (1) if it notices you wildcarded the whole hashtabe, it just erases the whole table (2) It uses a simple loop if there isnt many to do, default below 10 to do, or -bN and u can set that number. (3) other wise it uses a Hsave & Filter combo If anyone is interested but cant follow it i can explain.

Ok, thanks DaveC, youa re the man...
The process is not called often, but when it does, it has to remove let say like 100 items or more from a 5000 items tables (more or less). This is the reason that a while loop takes ages.
I'm going to try some different methods. From what I have tested so far, using goto works 2 times faster than doing the same with a while (I have no idea why).
I'm going to try doing it with a 0 0 timer that will call a function that will remove each time the first line it finds until no lines are found, and then it stops the timer. I will then check how many ticks it takes..... :tongue:

Ok, Using a while loop takes exactly twince as much as it takes doing the same loop with Goto which breaks when the hash table is cleaned from the data I want.
It also appears that /timer 0 0 , is as fast as using goto.
I'm going to try the idea of DaveC and see if it can speed things up a little, or if it works well with my data.

Dave, your method of using /filter is working amazingly fast. WOW!!! Thanks.
