Example in ST:
VarSTRING1 := REPLACE ('SUXYSI','K',2,2);
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.
FIND
Provided by standard.lib.
FIND searches for a partial string within a string.
The input variable STR1 and STR2 are type STRING, the return value of the function is
type STRING.
FIND(STR1, STR2) means: Find the position of the first character where STR2 appears
in STR1 for the first time. If STR2 is not found in STR1, then OUT:=0.
Example in IL:
LD 'abcdef'
FIND 'de'
ST VarINT1 (* Result is '4' *)
Example in FBD:
