   RUN FileName;	Run A File in sub-fork
   EXEC();              Run Exec
   EMACS();             Run EMACS
   MM();                Run MM
   FileP FileName; 	Test If File exists
   CMDS (!%L);          Submit List of commands (FEXPR)
   DoCmds (L);          Submit List of commands (EXPR)
                        Use CRLF or BL in string
   VDIR (L);            DoCmds LIST("VDIR ",L,CRLF,"POP");
   HelpDir();           DoCmds  LIST("DIR PH:*.HLP",CRLF,"POP");
   Take (FileName);     DoCmds LIST("Take ",FileName,CRLF,"POP");
   SYS (L);             DoCmds LIST("SYS ", L, CRLF, "POP");
   TALK (L);            DoCmds LIST("TALK ",L,CRLF);
   TYPE (L);            DoCmds LIST("TYPE ",L,CRLF,"POP");

Fork manipulation:  [return forkhandle, FH, an integer returned by system]
   OPENFork FileName; 	 	Get a File into a Fork
   RUNFork FH;	 	        Normal use, to run a Fork
   KILLFork FH;	 	        Kill a Fork
    GetFork Jfn; 	 	Create Fork, READ File on Jfn
    STARTFork FH;	 	Start (Restart) a Fork
    WAITFork FH;	        Wait for completion

File manipulation functions:    [Mostly return JFN, as small integer]
   GetOLDJfn FileName; 	        test If file OLD and return Jfn
   GetNEWJfn FileName; 	 	test If file NEW and return Jfn
   RELJfn Jfn;	 	        return Jfn to system
   OPENOLDJfn Jfn;	 	OPEN to READ
   OPENNEWJfn Jfn;	 	Open to WRITE
   GTJfn FileName; 	        Get a Jfn
   NAMEFROMJfn Jfn;	 	name of File on a Jfn


Miscellaneous Functions:
   GetUNAME(); 	 	        Get USER name
   GetCDIR();	 	        Get Connected DIRECTORY
