GENLVL(nn)
GENLEVL(nn) specifies the severity level that determines if a module or program object is created. The severity level, nn, corresponds to the severity level of the messages produced during compilation.
You can specify a one or two-digit number, 0 through 30, which is the severity level you want to use to determine if a module or program object is to be created. No module or program object is created if errors occur with a severity level equal to or greater than this severity level.
The default value for GENLVL is 30. GENLVL(0) cancels compile.
