[Function] Store in the variable specified in operand 1 the status (program error number) of
the program specified in operand 2.
(Note 1) If the obtained result is “0”, it means no program error is present.
(Note 2) Although the error lists are written in hexadecimals, the status to be stored
(program error number) is a decimal.
Therefore, the decimal program error numbers must be converted to
hexadecimals.
[Example] PGST 1 2 Read the error number for program No. 2 to
variable 1.
