Label field

Code a label on every CNTL statement, as follows:

The label must begin in column 3.
The label is 1 through 8 alphanumeric or national ($, #, @)characters.
The first character must be alphabetic or national ($, #, @)
The label must be followed by at least one blank.
The label may be preceded by up to 8 alphanumeric or national characters, and then separated by a period. Coding the label in this way should not be confused with specifying an override, as can be done when coding DD statements.
