- Insertion of IMPLICIT NONE
- Specification and systematic modification of data sizes
Facilities Provided for Evaluation Purposes Only
Under the terms of the shareware and evaluation license, the following facilities may be used on small programs for the purposes of evaluation only:
Report generation for the entire program
Including:
- Symbol table listing (LIST SYMBOLS)
- COMMON block listing in address order (LIST COMMON BLOCKS)
- Call structure listing (LIST CALL STRUCTURE)
QA checks across the entire program
Including:
- Checking for inconsistent arguments
- Checking for misaligned objects in COMMON, EQUIVALENCE and STRUCTURE
- Checking for accidental EQUIVALENCE and EQUIVALENCE of mixed type and size
- Checking for consistency in the use of names
- Checking for variables which are read but never written or written to but never read
- Checking for inconsistent usage of data types (e.g. INTEGER for LOGICAL)
- Checking for multiple initialization of data in COMMON blocks
Facilities for the support of migration
Including:
- Automatic insertion of header files in all sub-programs
- Insertion of code for run-time translation of file names
- Insertion of argument counts in routines with variable numbers of arguments
