Arithmetic Parameters and Program Jumps
10.3 Conditional program jumps (IF, GOTOB, GOTOF, GOTO, GOTOC)
Fundamentals
422 Programming Manual, 11/2006, 6FC5398-1BP10-2BA0
Parameters
IF
Keyword for condition
GOTOB
"Jump statement" with backward jump destination (towards beginning of
program)
GOTOF
Jump statement with forward jump destination (toward program end)
GOTO
Jump statement with destination search first forward then backward
(first toward end of program and then toward beginning of program)
GOTOC
Suppress Alarm 14080 "Destination not found". Jump instruction with
destination search first forward then backward (first toward end of
program and then toward beginning of program)
<destination>
Branch destination parameters for label, block number, or string
variable
Label
Destination for a jump command
Label:
Labeling of destination within the program
Block number
Jump destination as main block or subblock number (e.g., 200, N300)
String variable
Variable of type string containing a label or block number
Comparison and logical operands
The jump condition can be programmed with any comparison or logic operation (result:
TRUE or FALSE). The program jump is executed if the result of the operation is TRUE.
The jump destination can only be a block with a label or block number that appears within
the program.
Note
Several conditional jumps can be formulated in the same block.
==
Equal to
<>
Not equal to
>
Greater than
<
Less than
>=
Greater than or equal to
<=
Less than or equal to
