variable container names

[kwinkler]

This should be simple, but I can't figure it out.

I would like to insert data into a series of variables inside a repeat loop. This code will not compile.

repeat with k = 1 to 2
put xhi after ("theData" & k)
end repeat

It gives the error - 'compilation error at line 511 (Chunk: bad destination) near "(", char 15'

But this code works fine.

put xhi after theData1
put xhi after theData2

Is there any way to make the repeat loop work correctly? Thanks in advance.

Hi...

look in the 'User guide' page 154... section 5.5.7... all will be made clear

be well

Dixie,

Thanks for the suggestion, but I don't see anything in section 5.5.7 that helps me. What is the trick?

Thanks,

hi...

If you are trying to make an array use [ ]...

Code: Select all

on mouseUp
   repeat with k = 1 to 30
      /* whatever value you choose to give xhi */
      put xhi into theData[k]
   end repeat
   
   repeat with count = 1 to 30
      put theData[count] into line count of fld 1
   end repeat
end mouseUp

This will list xhi 30 times into each line of fld 1... as I don't know what this variable contains...

be well,

Dixie

Dixie,

The names of the variables are 'theData1', 'theData2', etc. The '1' and '2' are not keys. I am trying to add new elements to the end of arrays named 'theData1', 'theData2', etc.

As I said, these lines work correctly-

put xhi after theData1
put xhi after theData2

Any ideas would be appreciated,

Ken

Hi Ken,

Maybe this script is useful for you

Code: Select all

on testSetGlob pText
   global thedata1,thedata2
   if pText = empty then
      put "xhi" into pText
   end if
   repeat with k = 1 to 2
      put pText&k into buf
      put "theData" & k into NomG
      do "put empty into"&& NomG
      do "put buf into"&& NomG
   end repeat
   put thedata1&return&thedata2
end testSetGlob

The construction you propose seems reasonable, but the LC parser, and HC before it, would not quite accept it. A "do" construction allows the parser another level of evaluation, and this is necessary for compilation.

on mouseup
repeat with k = 1 to 2
do "put xhi into" && "theData" & k
end repeat
end mouseup

Seems the same, as if the "do" is redundant. But it is not. This sort of thing pops up all the time. You get a feel for when you need to consider it, and more often, if what seems like perfectly logical code gives this sort of error, then you likely need to go that route after the fact.

Thank you to everyone who helped with this problem. My original code looked like this, and did NOT work-

repeat with k = 1 to 2
put xhi after ("theData" & k)
end repeat


By using the 'do' command, the code is re-written as follows, and this DOES WORK-

repeat with k = 1 to 2
do "put xhi after " && "theData" & k
end repeat

Now I need to study the 'do' command to find out why this works. I had never heard of this command before.

You might also consider using an array, in which you could store all your data in one variable with named slots:

put "something" into tData[1]
put "somethingelse" into tData[2]

Not a sophisticated answer:

repeat with k = 1 to 2
put “theData” & k into theData
put xhi after theData
end repeat
