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

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.

with the character in the P position.

REPLACE 'K',2,2

ST VarSTRING1 (* Result is 'SKYSI' *)
