:Invoking the Assembler

     The CP/M Assembler is invoked by typing --

          ASM filename   or   ASM filename.parms

where 'filename' is the name of the file 'filename.ASM' to be assembled.

     In the case of the first command, the following files are created --

          filename.HEX        - "HEX" file containing machine code in
                                Intel hex format
          filename.PRN        - listing file


     Iî  thå caså oæ thå seconä command¬  theså fileó arå createä accordinç �
to the parameters specified --

          ASM filename.pqr

where
          p : A,B,...  - designates the disk name which contains the source
          q : A,B,...  - designates the disk name to receive the hex file
              Z        - skips generation of the hex file
          r : A,B,...  - designates the disk name which will receive the
                         print file
              X        - outputs the listing to the console
              Z        - skips generation of the print file

     NO SOURCE FILE PRESENT        The file specified in the ASM command
                                   does not exist on disk

     NO DIRECTORY SPACE            The disk directory is full, erase files
                                   which are not needed, and retry

     SOURCE FILE NAME ERROR        Improperly formed ASM file name

Š     SOURCE FILE READ ERROR        Source file cannot be read properly by
                                   the assembler, execute a TYPE to
                                   determine the point of error

     OUTPUT FILE WRITE ERROR       Output files cannot be written properly,
                                   most likely cause is a full disk, erase
