Fortran and Language Environment runtime options comparison

Table 1. Fortran and Language Environment runtime options
Fortran option	Language Environment equivalent	Notes®
ABSDUMP \| NOABSDUMP	TERMTHDACT	TERMTHDACT(DUMP) replaces ABSDUMP to produce a Language Environment dump at termination, but there is no automatic mapping. TERMTHDACT with suboptions TRACE, QUIET, MSG, UATRACE, UAONLY, or UAIMM replaces NOABSDUMP to avoid getting a Language Environment dump at termination.
AUTOTASK \| NOAUTOTASK	AUTOTASK \| NOAUTOTASK	AUTOTASK \| NOAUTOTASK provides behavior compatible with VS FORTRAN Version 2.
CNVIOERR \| NOCNVIOERR	Not applicable	There is no Language Environment equivalent for CNVIOERR \| NOCNVIOERR. Fortran semantics are as though CNVIOERR were in effect.
DEBUG \| NODEBUG	Not applicable	There is no debugger support for Fortran.
DEBUNIT	Not applicable	There is no Language Environment equivalent for DEBUNIT.
ECPACK \| NOECPACK	Not applicable	There is no Language Environment equivalent for ECPACK \| NOECPACK. You cannot run programs with Language Environment that use access registers or that were compiled with the EC or EMODE compiler options.
ERRUNIT	ERRUNIT	ERRUNIT provides behavior compatible with VS FORTRAN Version 2.
FAIL	ABTERMENC	ABTERMENC replaces FAIL, but there is no automatic mapping. ABTERMENC controls whether a condition of severity 2 or greater is terminated with a return code or an abend. ABTERMENC(RETCODE) is similar to FAIL(RC), and ABTERMENC(ABEND) is similar to FAIL(ABEND).
FILEHIST \| NOFILEHIST	FILEHIST \| NOFILEHIST	FILEHIST \| NOFILEHIST provides behavior compatible with VS FORTRAN Version 2.
INQPCOPN \| NOINQPCOPN	INQPCOPN \| NOINQPCOPN	INQPCOPN \| NOINQPCOPN provides behavior compatible with VS FORTRAN Version 2.
IOINIT \| NOIOINIT	Not applicable	There is no Language Environment equivalent for IOINIT \| NOIOINIT. The message file is opened either when the first record is written to it or when an OPEN statement refers to error message unit. If no allocation for the ddname has been made for the message file, it is dynamically allocated to the terminal (under TSO) or to SYSOUT=* (under z/OS batch).
OCSTATUS \| NOOCSTATUS	OCSTATUS \| NOOCSTATUS	OCSTATUS \| NOOCSTATUS provides behavior compatible with VS FORTRAN Version 2.
PARALLEL \| NOPARALLEL	Not applicable	There is no Language Environment equivalent for PARALLEL \| NOPARALLEL. Parallel programs cannot be run with Language Environment.
PC \| NOPC	PC \| NOPC	PC specifies that Fortran static common blocks with the same name but in different load modules do not refer to the same storage.
PRTUNIT	PRTUNIT	PRTUNIT provides behavior compatible with VS FORTRAN Version 2.
PTRACE \| NOPTRACE	Not applicable	There is no Language Environment equivalent for PTRACE \| NOPTRACE. Parallel programs cannot be run with Language Environment.
PUNUNIT	PUNUNIT	PUNUNIT provides behavior compatible with VS FORTRAN Version 2.
RDRUNIT	RDRUNIT	RDRUNIT provides behavior compatible with VS FORTRAN Version 2.
RECPAD \| NORECPAD	RECPAD(OFF \| NONE \| VAR \| ALL \| ON)	NORECPAD automatically maps to RECPAD(OFF). Fortran does not support RECPAD(VAR). RECPAD must be changed to RECPAD(ON).
SPIE \| NOSPIE STAE \| NOSTAE	TRAP(ON,SPIE) TRAP(OFF)	If either SPIE or STAE is specified or defaulted in input, TRAP is set to TRAP(ON,SPIE). If both NOSPIE and NOSTAE are specified, TRAP is set to TRAP(OFF). TRAP(ON,SPIE) is the recommended setting.
XUFLOW \| NOXUFLOW	XUFLOW(ON \| AUTO) XUFLOW(OFF)	There is no automatic mapping of XUFLOW to the Language Environment XUFLOW. NOXUFLOW maps to the Language Environment XUFLOW(OFF), which provides compatible behavior.
