gtpm1m2v | TPF V4R1 Migration Guide: 3.1 to 4.1 |
In the TPF 4.1 system, synchronous link control (SLC) support changed in two ways:
To use SLC support in the TPF 4.1 system, you need to use the number of messages on the input list (rather than core block levels) to set the shutdown and restart levels for SLC processing. These levels are specified on the AIDWN and AIRES parameters of the CCPPOL macro.
There are also internal changes that do not require any action on your part:
VM=NO
on the SIP CONFIG macro no longer affects the assembly of the following SLC control program segments:
In addition, coding VM=NO on the SIP CONFIG macro no longer affects the following E-type programs:
This code is now assembled as if you coded VM=YES, regardless of whether you are generating a system to run under VM.
