Old tcl code to new format

[RDB]

Hi,

I'm hoping someone can help me. I am working with some code which was written 10years or so ago which uses the commands

gFunEvaluator Basic
gradGEvaluator FiniteDifference -pert 1000

Having searched the internet it would appear that both of these commands have been updated to distinguish that they are tcl commands. From what I have found, similar commands are now written as:

functionEvaluator Tcl -file "Analyze -1"
gradientEvaluator Implicit (although i've replaced this with "FiniteDifference -pert 1000")

Could someone confirm if this is correct or if not, what are the updated versions of these commands.

Thanks,

Ross
