Flow Control Tools - Sharp EL-9900 Operation Manual

Chapter 13: Programming Features

6. Flow control tools

The calculator has the common flow control tools such as Goto - Label loop struc-
tures, and If-, For- and While-statement clauses for enhancing a program's efficiency.
It also has the capability for subroutines.
It is recommended to use If, For or While statements rather than Goto-Label loop
structures.
To access the flow control tools, use the P B BRNCH menu.

by colons(:) that are evaluated as a single line.

items.
* Use a comparison operand in a condition statement.
* Up to 115 If clauses can be nested, though if combined with
other types of loops, the maximum nested loop number may
vary due to the memory capacity.
