C/C++ Doesn't Allow Instream Compiles with CSECT option
 Technote (troubleshooting)
 
Problem(Abstract)
CBC3575 or CBC1742 Csect option is ignored due to naming error.
// EXEC PGM=CCNDRVR,PARM=CSECT
//SYSIN DD *
#pragma csect(CODE,"hello")
Before the pragma is used by the compiler, the compiler tries to assign a name by looking at the input data set name.
 
Cause
The compiler can't deduce a name from the SYSIN DD * so it gives that error and quits. There is no warning in the C/C++ Language reference book or in the C/C++ User's Guide against this. The CSECT compiler option is processed first and fails because of the absence of a qualifer, the #pragma does not have a chance to be processed and override. Therefore, the CSECT option should not be used without a qualifier when dealing with inline source. In this case, either an explicit qualifier should be used with the CSECT option or NOCSECT should be used for the #pragma to come into effect. As the order of CSECT processing is documented in the C/C++ User's Guide, this behaviour is correct.
 
Resolving the problem
Use compile option CSECT(hello), with or without the #pragma csect, or to use NOCSECT with the #pragma csect.
