Acceleration of TNS HP COBOL Programs
Acceleration of TNS HP COBOL Programs
The process of acceleration applies only to object files created in TNS mode by the
COBOL85 compiler (or by the cobol utility in the OSS environment of a TNS/R
system). Natively compiled programs cannot be accelerated. Accelerated object code
improves the execution speed of TNS programs on TNS/R systems. To accelerate a
TNS object file, use The Accelerator on page 6-24.
Figure 6-3 shows an SQL program file that has accelerated object code.
Caution. Because the Accelerator invalidates SQL program files, run the Accelerator before
you explicitly SQL compile the program to avoid having to recompile.
