Use this system macro to release a lock on an entry in the terminal address
table (WGTA) that was locked previously by the LWGTC macro.
Format
- SUFFIX=character
- The argument specifies the suffix to be used for WGTA addressing.
This is an optional parameter.
Entry Requirements
R9 must contain the address of the ECB being processed.
Return Conditions
- Control is returned to the next sequential instruction (NSI).
- Upon return, the WGTA entry is released.
Programming Considerations
- This macro can be run on any I-stream.
- The RWGTC must be issued on the same I-stream as the corresponding
LWGTC.
- Addressability to the WGTA item must have been established prior to the
use of this macro.
- The name of the WGTA lock byte is WG0LCK.
- The RWGTC macro must be issued in 31-bit mode since the WGTA can lie above
16 MB.
Examples
