VB Rate Function - 4gl Equivalent

[jademalo]

Hi,
I need to re-write a VB system using Progress 4GL and wondered if anyone has written an equivalent to the VB Rate function as I don't fully understand the logic and need to mirror this maths calculation?
Thanks,
David

This is the VB code that I am tring to convert. Has anyone ever come across this in 4gl?

vyield = Rate(term, (((vterm * vrate / 1200) + 1) * vbalfin# / vterm), -vbalfin#) * 12

There is no built-in support for 'financial' functions in ABL (strangely enough for a business language one might say)... this doesn't mean that those can't be implemented as an add-on package

If you're feeling like implementing the RATE() function you might find this helpful:
