Doug, if you lived nearer to me I would buy you a drink this evening! That
is exactly what I wanted and it works beautifully!
Thank you!
Brian

var string temp
; Run the sayLine function.
let temp = "sayLine"
formatStringWithEmbeddedFunctions("<" +temp +">")
; Run the sayLine script.
let temp = "$sayLine"
formatStringWithEmbeddedFunctions("<" +temp +">")
; Run something with arguments.
let temp = "sayString(\"Hi there!\")"
formatStringWithEmbeddedFunctions("<" +temp +">")
; Get a function's return value too.
let temp = "sysGetDate()"
var string result
let result = formatStringWithEmbeddedFunctions("<" +temp +">")
sayString("The current date is " +result)
You can run almost anything like that. There are a few limitations on
temp though: No variable references, no nested function calls, and
embedding quotes in an argument is difficult if not impossible. As far
as return values go, everything comes back as a string. You can't get
an object pointer back, but you can get window handles, integers, etc.
and convert them back from string to native type.
The formatStringWithEmbeddedFunctions function is pretty much what
made BX possible back in 2003.

Hi everyone!
I am creating some scripts to help out a jaws user. It's quite an
interactive project which is almost complete but I have a question if anyone
can please help.
I have the name of a jaws script contained within a text string, called
temp. What I want to do is run a jaws script based upon the text stored
within the string. So, if jaws is aware of the fact that the string temp
contains the words SayLine, I want it to run the script for SayLine, reading
the current line. Is it possible please to do this?
Thanks.
