A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Delete characters in a string.
Inputs
IN : STRING Character string
NBC : DINT Number of characters to be deleted
POS : DINT Position of the first deleted character (first character position is 1)
Outputs
Q : STRING Modified string.
Remarks
The first valid character position is 1. In FFLD language, the operation is executed only if the input rung (EN) is TRUE. The output rung (ENO) keeps the same value as the input rung.
In IL "Instruction list"
This is a low-level language and resembles assembly, the first input (the string) must be loaded in the
current result before calling the function. Other arguments are operands of the function,
separated by comas.
