       Name: write_0346                                              [Show more]
       Type: Subroutine
   Category: Tube
    Summary: Update the value of LASCT by sending a write_0346 command to the
             I/O processor
    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * DEATH calls write_0346
             * Main flight loop (Part 3 of 16) calls write_0346
             * TTX66 calls write_0346


 Arguments:

   A                    The new value of LASCT


.write_0346

 PHA                    \ Store the new value of LASCT on the stack

 LDA #&97               \ Send command &97 to the I/O processor:
 JSR tube_write         \
                        \   write_0346(value)
                        \
                        \ which will set the I/O processor's copy of LASCT to
                        \ the given value

 PLA                    \ Send the parameter to the I/O processor:
 JMP tube_write         \
                        \   * value = the new value of LASCT that we stored on
                        \             the stack
                        \
                        \ and return from the subroutine using a tail call
