Delete an item

[RossG]

I have a variable theString with numbers "4,6,21,3,32..." etc.
and a variable tVar with numbers "1,2,3,4....36"

I want to loop through the numbers in theString and delete the
same number from tVar...

repeat with m = 1 to 36
put m & "," after tVar
end repeat

repeat for each item theItem in theString until the number of items in tVar < 11
if theItem is among the items of tVar then
---delete item .....
end if
end repeat

I've tried a number of ideas for the line ---delete item etc. but all so far all delete item number
theItem and not the number.

A curious thing: one of the variations I tried delete the line of code!!!

Help appreciated.

Hi Ross,

try again but use:
-> itemoffset
and first
-> set the wholematches to true

Because 4 is in 4,14,24 and 34!
You get the picture

Code: Select all

repeat for each item theItem in theString until the number of items in tVar < 11

You can't combine "repeat for each" and "repeat until" structures. Do this instead:

Code: Select all

repeat for each item theItem in theString
    if the number of items in tVar < 11 then exit repeat 
    .... 
end repeat

Related, but different!

I have a field which displays a record number, tab, then a string of numbers thus:-

Code: Select all

55    1,2,3,12,17,23,32, 

I want to delete a line in which a number appears e.g if aNumber is 3 I want to
delete this record from the field.

My efforts so far falls over because the "55" isn't an item (or some other reason?)

Help appreciated.

assuming here that line 1 of fld 1 = 55 & tab & 1,2,3,12,17,23,32

Code: Select all

55	1,2,3,12,17,23,32

The line is tab delimited, so item 1 of the line = 55 and item 2 of the line = 1,2,3,12,17.23.32...
To get at the items of item 2 of the line, change the itemdel to comma...

to delete a number from the record...

Code: Select all

on mouseUp
   put line 1 of fld 1 into tempRecord
   set itemDel to tab
   put item 2 of tempRecord into tempVar
   set itemDel to comma
   
   repeat with count = 1 to the number of items of tempVar
      if item count of tempVar = 3 then
         delete item count of tempVar
      end if
   end repeat
   
   put tempVar
end mouseUp

or delete the whole record if the number 3 appears anywhere in the record

Code: Select all

on mouseUp
   put line 1 of fld 1 into tempRecord
   set itemDel to tab
   put item 2 of tempRecord into tempVar
   set itemDel to comma
   
   if 3 is among the items of tempVar then
      set itemdel to tab
      delete item 2 of tempRecord
   end if
   
   put tempRecord
end mouseUp
