Example in ST:

Var1 := DELETE ('SUXYSI',2,3);

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.

REPLACE

Provided by standard.lib.

REPLACE replaces a partial string from a larger string with a third string.

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

REPLACE(STR1, STR2, L, P) means: Replace L characters from STR1 with STR2 beginning
with the character in the P position.

Example in IL:

LD 'SUXYSI'

REPLACE 'K',2,2

ST VarSTRING1 (* Result is 'SKYSI' *)
