OpenVMS ALPBASR03_062 Alpha V6.2x BASIC Run-Time Library ECO Summary

TITLE: OpenVMS ALPBASR03_062 Alpha V6.2x BASIC Run-Time Library ECO Summary Modification Date: 18-MAY-1999 Modification Type: New Kit This kit supersedes ALPBASR02_070 for OpenVMS Alpha V6.2x only. NOTE: An OpenVMS saveset or PCSI installation file is stored on the Internet in a self-expanding compressed file. The name of the compressed file will be kit_name-dcx_vaxexe for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha. Once the file is copied to your system, it can be expanded by typing RUN compressed_file. The resultant file will be the OpenVMS saveset or PCSI installation file which can be used to install the ECO. Copyright (c) Compaq Computer Corporation 1996, 1999. All rights reserved. PRODUCT: OpenVMS Alpha COMPONENT: BASIC Run-Time Library (BASRTL) SOURCE: Compaq Computer Corporation ECO INFORMATION: ECO Kit Name: ALPBASR03_062 ECO Kits Superseded by This ECO Kit: ALPBASR02_070 (For OpenVMS Alpha V6.2, V6.2-1H1, V6.2-1H2 and V6.-2-1H3) ALPBASR01_070 ALPBASR02_062 ALPBASR01_062 ECO Kit Approximate Size: 1152 Blocks Kit Applies To: OpenVMS Alpha V6.2, V6.2-1H1, V6.2-1H2, V6.2-1H3 System/Cluster Reboot Necessary: No Installation Rating: INSTALL_3 3 - To be installed on all systems running the listed versions of OpenVMS which are experiencing the problems described. Kit Dependencies: The following remedial kit(s) must be installed BEFORE installation of this kit: None In order to receive all the corrections listed in this kit, the following remedial kits should also be installed: None ECO KIT SUMMARY: An ECO kit exists for DEC$BASRTL.EXE OpenVMS Alpha V6.2 through V6.2-1H3. This kit addresses the following problems: Problems address in ALPBASR03_062: o The BASIC function DATE$() formats the year as only two digits. o An incorrect SCAFACINT message appears when ASTs are used. o A BASIC output routine, when run in BATCH, does not properly account for international characters (high-bit-on). This problem causes a variety of strange output, depending on how many such characters are being printed. For example, if the command PRINT STRING$(999%,ASCII("é")) is run in batch (BASIC V3.4), the error "%BAS-F-MEMMANVIO, Memory management violation" occurs. o Under DEC BASIC with DEC$BASRTL V01-017, error #35, "Memory Management Violation", is incorrectly issued when a second open statement is used to connect an I/O stream to a remote file already opened. The correct error would be error #12, "Fatal System I/O Failure". Below is an example for a file to be opened twice over the network, so that a secondary access to the same data is created. Assume that "ixfile" is a logical name defined to point to a file on another node. The second open statement returns BASIC ERR=35, which cannot be trapped, so the program must abort. MAP (ixfile) STRING the_item ! First, create a sample file. OPEN "ixfile" FOR OUTPUT AS FILE #1, INDEXED FIXED, & PRIMARY KEY the_item, MAP ixfile CLOSE #1 ! Open the newly created file. OPEN "ixfile" FOR INPUT AS FILE #1, INDEXED FIXED, & ACCESS READ, ALLOW MODIFY, MAP ixfile ! Attempt to open the same file and connect an I/O stream to the remote file ! already opened (ERR=35 will result) OPEN "ixfile" FOR INPUT AS FILE #2, INDEXED FIXED, ACCESS & READ, ALLOW MODIFY, MAP ixfile, CONNECT #1 o Under some conditions, a traceback list from a fatal error in a DEC BASIC program indicates some incorrect line numbers. Also, certain I/O failures report the wrong error code due to an I/O error recovery problem. NOTE: In order to get the full effect of this fix, the ALPTRAC02_062 kit should be installed. Problems addressed in ALPBASR02_070 for OpenVMS Alpha V6.2x: o A BASIC program may ACCVIO or hang in an infinite loop in DEC$BASRTL if AST calls a BASIC routine. Problems addressed in ALPBASR01_070: o The last build got a link warning from another facility. Problems addressed in ALPBASR02_062: o Did not properly account for linked chain of XABs, some of which needed virtual memory to be freed. Problems addressed in ALPBASR01_062: o Matrix multiply of D-Float types always produces integer results. o The lib$signal of an error produced a fatal and aborted program, preventing other handlers' recovery. o Lib$signal caused program to lose local dynamic store, and execute incorrect code. INSTALLATION NOTES: The system does not need to be rebooted after this kit is installed. However, if you have other nodes in your OpenVMS VMScluster, they should be rebooted or you should install this kit on each system in order to make use of the new image(s).
