FOR

FOR

---

FOR loop_var = start TO stop [STEP step]

Initiates a FOR to NEXT loop.

Initially, loop_var is set to start. Then, the statements between the FOR statement and the NEXT statement are executed and loop_var is incremented by step (if step is not specified, by 1). This is repeated until loop_var has become greater than stop. Execution then continues at the statement following NEXT. The value of loop_var equals stop+step after the loop.

Parameters

• loop_var is a numeric variable.
• start, stop and step are numeric expressions.

Errors

• No NEXT statement is found to match the FOR statement: FOR without NEXT occurs at the FOR statement.
• loop_var is a string variable or start, stop, or end has a string value: Type mismatch.
• loop_var is an array element: Syntax error.
• loop_var is an integer variable and a start, stop or step is outside the range [-32768, 32767]: Overflow.
