INSERT

Function - Insert characters in a string.

Inputs

IN : STRING   Character string
STR : STRING  String containing characters to be inserted
POS : DINT    Position of the first inserted 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.
