Hi Fabio

I put in wait windows at all the points you mentioned

>? type( THIS.CheckSource )
C

>? vartype(poText)
O

> ? message()
Nothing happended, the code went on to execute further

WAIT WINDOW type( THIS.CheckSource )
WAIT WINDOW  vartype(poText)
*try
***===> evals okay
cContents = EVALUATE(THIS.CheckSource)
*catch
* WAIT WINDOW  message()
*ENDTRY

cSource   = THIS.CheckSource
***===> macros okay
cContents = &cSource.

cSource   = THIS.CheckSource
***===> evals fails
cContents = EVALUATE(cSource)

So I guess coming via into variables it does have a problem. Thanks I guess this solves the problem, or raises more questions?
