JP
FUNCTION: Jump to Program Location
DESCRIPTION:
The JP command causes a jump to a program location on a specified condition. The program
location may be any program line number or label. The condition is a conditional statement
which uses a logical operator such as equal to or less than. A jump is taken if the specified
condition is true.
Multiple conditions can be used in a single jump statement. The conditional statements are
combined in pairs using the operands “&” and “|”. The “&” operand between any two
conditions, requires that both statements must be true for the combined statement to be true.
The “|” operand between any two conditions, requires that only one statement be true for the
combined statement to be true. Note: Each condition must be placed in parenthesis for
proper evaluation by the controller.

Hint: JP is similar to an IF, THEN command. Text to the right of the comma is the condition that must be
met for a jump to occur. The destination is the specified label before the comma.
