Sequence
The screen called via the asynchronous MMC command continues to be displayed
until one of the two configured softkeys is actuated:
With softkey "END", the user dialog is immediately exited.
With softkey "Screen2", a further screen is then displayed for 10s.
Program
• The acknowledgment variable is defined as a string.
Length of the string: >= 20
(Values < 20 are evaluated internally only,
SK0 ... SK15 are entered at position 17...20 on actuation of the softkey).
• The string is assigned a value in the parts program and any old softkey
information is deleted.
• Before the parts program can branch as a function of the acknowledgment
variable, the block search must be halted by the STOPRE command.
• IF Match (Quit_1," SK1") >= 0 GotoF Label1
searches for a string within the string
If no softkey is actuated, the loop runs again.
