LABEL:Grip statement
Label is a name which may precede any GRIP statement, except for the PROC statement. The label may be up to six characters in length, with no blank spaces, must start with a letter and must be immediately followed by a colon.
NOTE: GRIP allows a
total of 1000 labels per subroutine. The DO loop generates two labels, the CALL
command generates a label, and the IFTHEN/ELSE/ELSEIF/ENDIF uses 2 labels plus 1
for every ELSEIF. These labels count against the total you can use.
