Isn't it on the tail of the command; something like

  BASIC -quit ADFS::0.$.The.Path.To.My.Program 

This is how RISC OS runs BASIC programs that you double-click on, or call
via *Filer_Run, or whatever.

From this, you can get the path into a path$ variable as follows:

  buffer_size% = 1024
  DIM buffer% buffer_size%

  REM Read the command line used to call the program.

  SYS "OS_GetEnv" TO environment%
  SYS "OS_ReadArgs", ",load=quit/K", environment%, buffer%, buffer_size%

  SYS "XOS_GenerateError", buffer%!0 TO basic$
  SYS "XOS_GenerateError", buffer%!4 TO path$

  REM We're assuming that we're being run by a double-click, and so the
  REM command line will start "BASIC -quit ...". If not, we don't go
  REM any further.

  IF basic$ <> "BASIC" OR path$ = "" THEN END

  PRINT "My file is ";path$
