"do" statements and value function

[Francis Nugent Dixon]

Hi from Beautiful Brittany,

I agree with Tim.

Firstly, I use "Do" functions every day, and run
up "Do" statements of many lines (building it up
in a variable). effectively making mistakes in
the generation until I get it right !

Couldn't do without the "Do" statement, but I guess
that many LiveCoders don't find a use for it.
I used to use it much more in Hypercard.

As a simple example (watch out for wraps) :
    --
    --     Build AppleScript to call Skim, in my variable  
"LVMasterScript"
    --
    put LVDataPath & field "MyFileName" into LVFilePath       -- Build  
Full File Path from Partial and File Name.
    put "set LVFilePath to POSIX file " & quote & LVDataPath & field  
"MyFileName" & quote into line 1 of LVMasterScript
    put "tell application " & quote & "Skim" & quote into line 2 of  
LVMasterScript
    put "set myDocument to open LVFilePath" into line 3 of  
LVMasterScript
    put "tell myDocument" into line 4 of LVMasterScript
    put char 1 to 3 of field "MyPages" into LVPage    -- Pick up Page  
Number.
    if field MyScaleFactor is empty then put "2.0" into field  
MyScaleFactor     -- Take default scale value.
    put field MyScaleFactor into LVScaleFactor
    put "set view settings to {scale factor:" & LVScaleFactor & ",  
auto scales:false}" into line 5 of LVMasterScript
    put "go to page " & LVPage into line 6 of LVMasterScript
    put "end tell" into line 7 of LVMasterScript
    put "activate" into line 8 of LVMasterScript
    put "end tell" into line 9 of LVMasterScript
    do LVMasterScript as AppleScript
