From: Daniel Dilts on 4 Jul 2010 14:44 I am writing a program in SysRPL that I would like to use the extable library from. If I understand correctly I would have to create a ROM pointer for each function in the library that I would like to use. The problem I have is how do I determine if there is a library at a given number, and also, how do I find what the numbers are for the different functions available in a library?
From: Jacob Wall on 4 Jul 2010 16:44 Hello, extable is library 258, or # 102, so that is the #lib number, and I see there are 5 named commands available, those would be 0 to 4. Something like this may do what you're thinking? Substitute ONE with the command you want. :: # 102 ONE #>ROMPTR ROMPTR@ ITE EVAL :: "Extable library not found!" FlashWarning ; ; From Programming in System RPL: #>ROMPTR ( #lib #cmd -> ROMPTR ) -- Jacob Wall On 04/07/2010 11:44 AM, Daniel Dilts wrote: > I am writing a program in SysRPL that I would like to use the extable > library from.

From: Daniel Dilts on 4 Jul 2010 17:20 That makes sense, but how do you get #102 from 258?

It could also be expressed in binary or octal.

You can actually just use 258 and the compiler _should_ create the appropriate system binary integer. :: 258 ONE #>ROMPTR ROMPTR@ ITE EVAL :: "Extable library not found!" FlashWarning ; ; Works just as well. |
