with the acknowledgment variable and evaluated in the parts program.

Parameters:
Dialog file (*.COM)
Text variable
Softkey
Program structure
The acknowledgment variable is defined as a string.
Length of the string: >= 20
;(Values < 20 are evaluated internally only,
entered at position 17...20 when a softkey is actuated).
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.
