Description:
This
application converts "old-style" ADAM/SSE routine prologues into the format generated
by the extended VAX Language Sensitive Editor STARLSE (SUN/105). The converted
prologue information may then be used as input to other SST applications which generate
documentation, help libraries, etc.
Usage:
PROCVT IN [OUT]
Parameters:
ATASK =
_LOGICAL (Read)
If ATASK is set to TRUE, then the style of output prologue will be
suitable for application programs (i.e. ADAM A-tasks). If it is set to FALSE, then prologues
suitable for ordinary subroutines or functions, such as a subroutine library, are produced.
[TRUE]
IN() = LITERAL (Read)
A list of (optionally wild-carded) file specifications which
identify the Fortran 77 source code files with "old-style" ADAM prologues which are to
be used for input. Up to 10 values may be given, but only a single specification such as
’.FOR’
is normally required. There is no limit on the number of program units which may be held in each
input file.
LANG = LITERAL (Read)
This value specifies the programming language
(i.e. the particular dialect of Fortran 77) in which the source code is written. It does not
affect the processing performed, but will be inserted into the output prologues under the
"Language" section heading. If a null (!) or blank value is given, then an appropriate STARLSE
placeholder will be used instead. The required entry can then be made later by hand. [’VAX
Fortran’]
OUT = FILE (Write)
The output file to which the source code will be copied
with its prologue format converted. If multiple input files are specified, then the converted
output will be concatenated into a single file. [PROCVT.FOR]
Examples:
PROCVT
MYPROG_OLD.FOR MYPROG_NEW.FOR
Reads the application program source code
held in the file MYPROG_OLD.FOR and converts its prologue information into STARLSE
format. The converted source code is written to the file MYPROG_NEW.FOR. PROCVT
.FOR
OUT=SUBS.FOR ATASK=FALSE LANG="Starlink Fortran 77"
Reads the source code for a subroutine library, held
in the files .FOR,
and converts its prologue information to STARLSE format. The converted source code is written to a single output
file SUBS.FOR. The language specified in the converted prologues will be "Starlink Fortran 77". PROCVT
IN=[".FOR",".GEN"]
NOATASK
In this example, a sequence of input file specifications is given. Each will be
processed in turn, converting its prologue information into STARLSE format. Output is written
to the single default output file PROCVT.FOR. Notes:
Due to the variety of layouts
found in existing "old-style" ADAM/SSE prologues, this application is not guaranteed
always to produce a perfect result. Particular problem areas are the inconsistent use of
indentation, and the occasional use of section headings and placeholders (of the form
’...’)
which do not quite match those given in the original ADAM/SSE prologue templates. Nevertheless,
in most cases, PROCVT will produce a result which can be edited fairly easily using STARLSE to
conform with the requirements of other SST applications. Appropriate STARLSE placeholders will be
inserted into output prologues to facilitate the entry of any essential information which cannot be
found in the corresponding input prologue.
Timing
The execution time is approximately
proportional to the total number of source code lines supplied for conversion. The time will be
increased somewhat if the code resides in a large number of separate files, due to the need to open and
close each file.
