Note These commands evaluate the expressions on either side, and return 1 if
true and 0 if false.
A Jump Commands
Goto ~ Lbl
Syntax Goto n : .... : Lbl n or Lbl n : .... : Goto n ( n is an integer from 0 to 9, or a
variable name from A through Z.)
Function Execution of Goto n jumps to corresponding Lbl n .
Example ?
→ A : Lbl 1 : ? → B : A × B ÷ 2 ^ Goto 1
Important! A Go ERROR occurs if there is no corresponding Lbl n in the same program
where Goto n is located.
Dsz (Decrement and Skip on Zero)
Syntax Dsz : : : ...
Function Decrements the value of by one. Then if the value
is non-zero, is executed, followed by and
everything after it in succession. If the value is zero, 1> is skipped, and and everything after it is executed.
Example 10
→ A : 0 → C : Lbl 1 : ? → B : B + C → C : Dsz A : Goto 1 : C ÷ 10
Isz (Increment and Skip on Zero)
Syntax Isz : : : ...
Function Increments the value of by one. Then if the value
is non-zero, is executed, followed by and
everything after it in succession. If the value is zero, 1> is skipped, and and everything after it is executed.
S
Syntax
1 S :
: ...
2 S : : ...
Function This is a conditional branching command. Conditional branching command
used in combination with relational operators (=,
≠ , >, >, <, <).
Syntax
1: is executed if the condition to the left of the S
command is true, and then and everything after it is executed
in sequence. is skipped if the condition to the left of the
S command is false, and then and everything after it is
executed.
Syntax
2: A non-zero evaluation result of the condition to the left of the S
command is interpreted as “true”, so is executed, followed
by and everything after it in succession. A zero evaluation
result of the condition to the left of the
S command is interpreted as “false”,
so is skipped, and and everything after it is
executed.
