Is indirect addressing possible?

[ajperks]

A text field is called Fld1
Can I put the text Fld1 into a variable and use that as the Field name?
It doesn't seem to work

Code: Select all

  put "Fld1" into temp
   put fld temp into fld "target"

This is working as expected here in 9.01 on Ubuntu 18.04

Work fine on my Mac.

I don't see how any of that other stuff could work.

Two possibilities:

1-

Code: Select all

on mouseUp
   put "Fld 1" into temp
   put temp into fld 2
end mouseUp

This puts "Fld 1" into fld 2.

2-

Code: Select all

on mouseUp
   put "Fld 1" into temp
   do "put " && temp &&  "into fld 2"
end mouseUp

This puts the contents of fld 1 into fld 2.

Was any of that what was intended?

The text of a field is a property, like width, height, and the others. While it's sometimes useful to be able to use the shorthand form of "put fld 1 into fld 2", the complete form of addressing a field property is useful here:

Code: Select all

put "MyFieldName" into tFld1
put the text of fld tFld1 into fld "SomeOtherField"

OK, I have found the problem.
The difference is between a software generated name and an explicit one when placed in a variable.
If the software generated name has invisible characters, the name you see is not the name the computer sees.

What I could do with is a quick running and clean bit of code that removes the letters Field from (say) Field2 (the clicked field and gives me the number 2 although the range might be up to and including 100) and no trailing spaces.

If you tell us what you are trying to do, maybe we can come up with a smart solution.

We move data between fields often. An example of a name containing characters preventing this, along with the code that isn't working, would be helpful.

Hi,

Can I put the text Fld1 into a variable and use that as the Field name?
It doesn't seem to work

Code: Select all

  put "Fld1" into temp
   put fld temp into fld "target"

This works here (LC 6.7.10):

Code: Select all

    put "myFldName" into myVar
    put "Hussah!" into fld (myVar)
    put fld (myVar)

This works, too:

Code: Select all

repeat with i = 1 to 4
    set the textstyle of btn ("c" & i & "_btn") to "plain"
    set the visible of grp ("G_" & i & "_grp") to false

The parentheses are not always required (i.e. sometimes it works w/o - just as with quotes for names), but help a lot to remember that this is a "constructed name".

For sure you must make certain that the name is spelled correctly - for this I omit anything but alphanumerics and "_" in my names, especially spaces.

At last, be sure to use the correct address - often it's a lacking "of me" or "of this cd" that causes confusion ...

Have fun!

Hi, Indirect addressing fields is entirely possible but care is needed to avoid including any spaces or other invisible codes into the name. In my case, it was Field(space) a number (space) The trailing space caused a lot of problems.

I needed to address a column of 100 fields, all enclosed in a group with a vertical scroll bar. The Flds were Named Field 1 … Field 100.
The address was placed in a variable.
