New to FM8 and still having a hard time with it.

So a question: is there a way to step through a value list in a loop? I would
like to be able to use FM8's ScriptMaker to do something like the following
using FM8's native scripting, not AppleScript. All of the items on the value
list and all of the output would be text values.

repeat with anItem in aValueList
doSomethingTo (anItem)
end repeat

Use the Loop script step -- something like this (not really
understanding what you're trying to do):

Set Field [gText, YourValueList]
Set Variable [$x = 0]
Set Variable [$y = valuecount(gText)]
Loop
New Record/Request
Set Variable [$x = $x+1]
Exit Loop If [$x > $y]
Set Field [MyTextField, getvalue(gText, $x)]
End Loop

Just a quick note to my last post. Old habits die hard. I made
efficient use of variables in my sample script, but I included a global
field (gText) that could itself be a variable, as well.

If your value list is based on a table then you can use Loop Script step
to work though the records and "do something" with them. Search for
"Loop Script Step" in FM8 help (I find you usually need to guess the
search words well in order to locate appropriate help with FM8 howver
this time "repeat" turned up the Loop function).
The Value List should reflect any changes you make to the underlying table.
Note that with FM8 a table does not have to be "related" to other tables
in the database file. It can just be there for the purpose of value
lists or reference data.

Thanks for any suggestions.

Max,

To perform a find this way, you have to fall back into those old habits
Howard did mention. When the variable coontains the value you need, put this
value in a global field.

Set Field [ gMyGlobal ; $MyVariable ]
Enter Find Mode [] (Disable the pause)
Set Field [ MySearchField ; gMyGlobal ]
Perform Find

I did not include any errortrapping

Thanks, Howard and Michael. Now I have the loop set up, and I'm
successfully
stepping through the text items of the Value List. My objective is to
automate a series of string searches, with the search criteria coming from
the Value List.

Unfortunately, I now realize that Perform Find seems only to accept text
as
criteria. For my script to work, I need it to accept variables. Yet when I
type in a variable ($gg), it just looks for the literal string "$gg." So
now
I'm hunting for a way around this.

Thanks again for help.

I think you can remove the first Set Field and replace gMyGlobal by
$MyVariable in the second.
