Hi Andrus

Its not a bug.

EXECSCRIPT() is like a call to a procedure;

because EXECSCRIPT("x=y") is compiled well,
esecution fail on procedure, not on the line where is the call.

muutsead()

PROCEDURE muutsead
cres = 'Do not touch'
ON ERROR  seterror()
cres = _EXECSCRIPT()
MESSAGEBOX(cres)

PROCEDURE seterror
RETURN TO muutsead
ENDPROC

PROCEDURE _EXECSCRIPT
 X=Y
ENDPROC

PROCEDURE seterror
RETURN TO muutsead
ENDPROC

EXECSCRIPT("x") fail at compiled time, on the line where it is executed,
then the assign value is not done.
