instructions cannot be compiled: The data compacting instructions:
PACK, PACKLOOP, PACKRS, and PACKAA The shift register
instructions: SSR, FTSR–IN and FTSR–OUT The PRINT instruction
The BCD instructions: BCDBIN and BINBCD Additionally, the CDT
and SDT instructions, when used in a compiled SF program or
subroutine, must specify a static table; that is, the table’s base address
must be a V, K, G, VMS, or VMM address and the table’s size must be
specified as a constant.

1.
Press the Insert key to turn the Ins mode on. See the Status Line
near the bottom of the screen.
2.
Use the arrow keys to position the parameter cursor (red or
highlighted box) in the last row of the Special Function
Program.
3.
Press Enter and the new row appears as the last row.
4.
Repeat Step 3 to enter additional rows.
Entering Special Function Program Instructions
You can enter instructions into your Special Function Program
efficiently using either the Instruction Bar or Menu Bar.
To enter instructions using the Instruction Bar:
1.
Move the pointer to the Instruction bar.
2.
Click with the left mouse button on the desired instruction on
the lower half of the Instruction Bar. If the desired instruction is
not displayed, click the appropriate instruction group on the top
half of the instruction bar.
