Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL 5.2 compiling and * * running programs that contain statements of * * the form INSPECT x CONVERTING y TO z, where * * y is a literal longer than 1 character and z * * is a figurative constant such as SPACES. * * * **************************************************************** * PROBLEM DESCRIPTION: Poor runtime performance. The COBOL * * program runs slower than an equivalent * * program compiled with earlier * * Enterprise COBOL compilers and exhibits * * increased CPU consumption. * * * **************************************************************** * RECOMMENDATION: Apply provided service. * **************************************************************** The compiler was not expanding the figurative constant to match the length of the first argument of the CONVERTING phrase, which would have allowed the conversion to be done inline with a TR instruction. Instead, the compiler chose to call an expensive library routine to handle the conversion, which introduced significant overhead to the processing.
Problem conclusion
The compiler was updated to handle this scenario with an inline TR instruction instead of a call to a library routine.
