Changes Affecting Version 6.1

The following paragraphs describe changes that can affect programs originally written with ACUCOBOL-GT Version 6.1.

Compiler Changes

Programs that will be deployed on 64-bit Windows systems and that have USAGE POINTER data items must be recompiled with Version 6.1.1 or later. This is because, beginning with Version 6.1.1 (the introduction of ACUCOBOL-GT for 64-bit Windows), the compiler and runtime differentiate between USAGE LONG and USAGE POINTER data items. This is necessary for 64-bit Windows.

Two compilation switches provide compatibility with Version 6.1:

`-C61`	Causes the compiler to generate code according to the rules used by Version 6.1.
`-Z61`	Creates object code that can be run with a Version 6.1 runtime.

Runtime Changes

Beginning with Version 6.2, on the HP e3000, if a program is compiled with the -Cp option, OPEN OUTPUT statements create temporary files. This is consistent with the behavior of native HP COBOL on the platform. Prior to Version 6.2, OPEN OUTPUT statements created permanent files.
Beginning with Version 6.2, C$OPENSAVEBOX makes use of the OPNSAV-FLAGS field of OPENSAVE-DATA. Prior versions ignored the field.
