FNADDR command

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 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 by Sirius Software 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.

The FNADDR command is available in Sirius Mods version 6.2 and later. The LOADMOD qualifier of FNADDR is available in Sirius Mods version 6.8 and later. The hex function number form of FNADDR is available in Sirius Mods version 7.2 and later.
