ASMA164W

Operand is a null string - record not punched
Explanation
A PUNCH statement does not have any characters between its two
apostrophes, or a single apostrophe to be punched as data is not represented
by two apostrophes.

The statement is ignored.

Programmer response
Correct the operand. If you want to "punch" a blank record,
the operand of the PUNCH statement should be a space enclosed in apostrophes.
