Note: This is a Sirius Mods-only command prior to Version 7.5 of Model 204.
The FNADDR command is used to determine the location in the Model 204 load module of a specified $function, or the location of the Fast/Unload load module, if the Fast/Unload User Language Interface is active.
FNADDR command syntax
FNADDR funcname | LOADMOD loadModName | + hexFuncNumber
The function name specified after FNADDR should not include the initial leading dollar sign (or pound in England). For example, this finds the location of the $Substr function:
FNADDR SUBSTR
This command is mostly useful for diagnosis of Model 204 internals problems, especially those related to $functions. It can also be useful in determining whether a particular $function is local, a former Sirius $function, or part of the Model 204 base.
If LOADMOD is specified, it is followed by the name of the load module to
locate.
Currently, the only load module name supported is FUNLOAD, so the following
command can be used for diagnosis when the Fast/Unload User Language Interface is active:
FNADDR LOADMOD FUNLOAD
If + hexFuncNumber. is specified, the number is that used in QTBL for
invocations of the $function.
