The following paragraphs describe changes that can affect programs originally written with ACUCOBOL-GT Version 6.1.
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. |
Beginning with Version 6.2, C$OPENSAVEBOX makes use of the OPNSAV-FLAGS field of OPENSAVE-DATA. Prior versions ignored the field.
