DELETE

Function - 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 LD 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, 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.
