VERSYS <wildspec> {/switches}

VERSYS displays version and resource information, about a runnable A-Shell program, that relates to the environment in which it was created. Normal runnable program extensions are .RUN, .LIT and .SBX.

The file version shown in the examples below can also be gotten from the DIR/V command. But DIR/V cannot tell you the details about the ashell and cmdlin resource files, which were used to compile the copy of DIR. Periodically we update these resource files, which when used to re-generate the LIT commands, may create subtle differences which are not reflected in the version number.

VERSYS.LIT shows the program header flags, which indicate how the program was compiled and whether it is compatible with AMOS. Note that it cannot distinguish whether /A was used when compiling (although it can distinguish /AV, which implies /A), and it cannot tell between /X:1, /X:2 and /D, all of which show as /X and are incompatible with AMOS.

Example1

.VERSYS SYS:DIR.LIT

DIR.LIT -- A-Shell Version & System Information:

   File Version:    1.5(125)

   System Resource: ashell[74]

   System Resource: cmdlin[24]: max devs = 300, max ppns = 512

History

2022 May, A-Shell 6.5.1716, VERSYS.LIT 3.0(110):  The /CSV switch outputs all the display details to a CSV for a wildcard set of programs. .

2022 May, A-Shell 6.5.1715, VERSYS.LIT 3.0(109):  The VERSYS display now includes many additional details about the specified program, memory requirements and the existence of embedded resources such as dynamic functions and embedded structure definitions.

2019 March, A-Shell 6.5.1657, VERSYS.LIT 3.0(108):  Now recognizes the new header signature and reports the minimum A-Shell version needed to run the program. For example:

.VERSYS MYPROG.RUN

MYPROG.RUN -- A-Shell Version & System Information:

   File Version:    1.0(100)

   Program format:  0xF276 (compil/x?; requires A-Shell edit 1657+)
