Using JMP 9.0.2 on Windows XP 32Bit

I want to produce a script which sets the formula of the column "Formula Column" to <<(:My Column) + 1>>. I need to reference "My Column" with a variable though. The following script makes the formula <<Eval(col) + 1>> which is meaningless...

col = column("My Column");

:Formula Column<<set formula(eval(col)+1);

There may be a simpler way, but this works in JMP 9 (Mac):

dt = Open**(**"$ENGLISH_SAMPLE_DATA/Big Class.jmp"**)**;

col=Column**(**"height"**)**<<get name;

newcol=dt<<new column**(**"Formula Column", formula**(**eval**(**evalexpr**(**expr**(**parse**(**col**))**+**1****))))**;

Re: Use a Variable for a column in Set Formula()

Thanks. For me I just needed:

newcol=dt<<new column**(**"Formula Column", formula**(**eval**(****(**parse**(**col**))**+**1****)))**;

Re: Use a Variable for a column in Set Formula()

**(**"height"**)**;. It would be much nicer if the formula changed to <<:height + 1>> so that it worked even if 'col' is being used for something else. Maybe too much to ask...

Yes, I noticed and removed the post quickly. Sorry for the confusion. Formula(Ascolumn(col)...) only works as long the global col is not cleared.
