8.35 Program Structures

January 2012

To design an easily understandable program, divide it into program sequences.

Use labels (LBL) as well as conditional and unconditional jumps. If you use

structured statements, the compiler creates the labels and jump commands.

Remember that using these labels and jump commands reduces the number

of available labels accordingly. You can nest structured statements in up to 16

levels. It is not possible to share levels.

Correct program structure

The statements IFT, IFF, WHILET, WHILEF, ENDW, UNTILT and UNTILF

require a valid gating result in the logic accumulator. They conclude the

sequence of gating operations. The statements ELSE, ENDI and REPEAT

require that all previous operations sequences have been concluded.
