Hi Ben,


If you want to get subsets of the list of System Functions printed the following might help.

Using Shallow[] gives a shortened list of the detailed Mathematica system functions loaded at the time of the function evaluation

Shallow[Column[Flatten[a={#,ToExpression[#]}&/@Names["System`$*"]],Spacings->1.5]]

To get the first few System Functions evaluated and printed Take[] for example the first 6 with the expression " startofSystemlist " defined below:

startofSystemlist:=Take[Flatten[a={#,ToExpression[#]}&/@Names["System`$*"]],12]

Column[startofSystemlist,Spacings->1.5]

To get the last few System Functions evaluated and printed Take[] for example the last 6 with the expression " endofSystemlist " defined below:

endofSystemlist:=Take[Flatten[a={#,ToExpression[#]}&/@Names["System`$*"]],-12]

Column[endofSystemlist,Spacings->1.5]



Cheers .... Syd
