Calcalator program

I've always been disappointed that VMS doesn't include a calculator program - even a four-function floating-point calculator would be very useful for DCL scripts.

What are other people using for simple FP calculations?

Re: Calcalator program

In pure DCL, when there appears to be a need for floating point calculations, then I tend to normalize down to a minimal base unit and work with that untill the final printout. So I'd do all the calculation in cents, or seconds, or percents, or bytes, or milliseconds, whatever was appropriate.

Check out the lexical function F$FAO or pretty printing.

Recently I find it more productive to just use PERL whenever/whereever I can.

hth,
Hein.

Re: Calcalator program

Hello Jack,

Just wanted to let you know that 64 bit calculation and floating point support
in DCL is something we are currently investigating. It might show up in one of the
next versions of the O/S.

What about sys$system:decw$calc.exe?

That sounds really nice Guy! What have you planned regarding additional control structures, such as loops?
