Coding and porting prerequisites

The standard of Fortran used for the coding of CHR is fundamentally Fortran 77, using the Starlink Fortran coding conventions described in SGP/16. Several common extensions to the Fortran 77 standard are used in source code for CHR, they are as follows:

The CHR library currently has no dependence upon any other package. To use CHR on any computer system porting effort is required only for those CHR routines which have operating system dependencies: these routines are listed in the following section.
