INSERT

Provided by standard.lib.

INSERT inserts a string into another string at a defined point.

The input variables STR1 and STR2 are type STRING, POS is type INT and the return value of the function is type STRING.

INSERT(STR1, STR2, POS) means: insert STR2 into STR1 after position POS.

Example in IL

LD ‘SUSI’

INSERT ‘XY’,2

ST VarSTRING1 (* Result is ‘SUXYSI’ *)

Example in FBD

Example in ST

VarSTRING1 := INSERT (‘SUSI’,’XY’,2);

Note

String functions are not “thread safe”: When using tasks, string functions may only be used in a single task. If the same function is used in different tasks, there is a danger of overwriting.
