A complete instruction list comprises:
.Line numbers
.Command from command store (see Section "Commands")
.Operand type
.Operand number
.Comment
The line number is automatically generated on entering a command.
The command, operand type, operand number and the comment must be transferred with ENT. The
cursor then jumps to the next positions within the instruction. The instruction is completed after the
comments are entered. If no comment is to be entered, the position is simply concluded the ENT.
Lines that are to contain only a comment should be started with a semicolon (;) instead of a
command. A comment can therefore cover several lines if each line commences with ";". A line
contains a maximum of 26 characters for the comment and may include all numeral, letters and
other characters on the keyboard.
A "find function" makes is easier to find certain operands.
If you wish to find a certain marker in the program listing, use the arrow keys to move the cursor to
a marker and press GOTO. Enter the number of the desired marker. Then press ENT to find the
marker.
