Below is a description of the variables in COMMON in the Fortran source code. They are used globally throughout PVT.
Variable Type* Description -------- ---- ----------- CONID S I Connection identifier, for <open workstation> CTLHND D I Tell PERHND whether to abort (0) or return (1) DUMCH S C Dummy character variables for future use DUMINT S I Dummy integer variables for future use DUMRL S R Dummy real variables for future use ERRIND D I Error indicator, returned from inquire functions ERRFIL S I PHIGS error file, for <open phigs> ERRSIG D I Signalled error code returned by PERHND ERRSW S I Indicates whether to send messages to operator FUNCID D C Function signalling the error, returned by PERHND GLBERR S C Absolute name of global message file GLBLUN S I Logical unit number of global message file IERRCT D I Count of errors detected by test IFLERR S I Controls writing of messages to message files INDLUN S I Logical unit number of individual message file MAXLIN S I Maximum characters per line in messages MEMUN S I Number of memory units, for <open phigs> PASSSW S I Controls writing/suppression of pass-messages PIDENT D C Unique program identifier - hierarchical number TESTCT D I Count of conditions tested so far within program TSTMSG D C Text for next condition to be reported. UNERR D I Count of unanticipated errors detected by test WKID S I Workstation identifier, for <open workstation> WTYPE S I Workstation type, for <open workstation> * S: Static value read from configuration file D: Dynamic variable, altered during test execution I: Integer C: Character R: Real
