Define Variate in MathCAD

[salchow27]

In MathCad, if I define A:= B+1, I must define B above A in order to get the A value. Is there any way that I can define B below A but still get the result. In excel I can do this....

Define as a function



f(b):=b+1

f(1.23456789)=2.23456789

Yes, but you have to be careful.

Use a global define operator, ≡ (press ~ to get it. Mathcad evaluates a worksheet in two passes. In the first pass, it evaluates any global definitions), then starting at the top again evaluates 'normal' definitions taking into account any global definitions.

See attached.

Thanks Stuart, that is what I want.

Could anyone advise how to define the variate in the attached file?

Use the Global Definition operator (key stroke ~)to define DD and B.
