$! JGRAPH.COM: Execute jgraph on VMS.
$ SAVE_VER = 'F$VERIFY( F$TRNLNM( "JGRAPH_VERIFY"))'
$ ! How to use this procedure:
$ ! (1) define a symbol to execute the command file
$ ! $ JGRAPH :== @dev:[directory]JGRAPH.COM
$ ! We will assume that both this jgraph.com and jgraph.exe reside
$ ! in dev:[directory].
$ ! (2) Then, to run the program with say the HYPERCUBE.JGR file,
$ ! $ JGRAPH HYPERCUBE ! (Yes you can leave off the .JGR extension)
$ ! To generate a stand-alone PostScript file that can be sent directly
$ ! to the printer, use:
$ ! $ JGRAPH HYPERCUBE "-P"
$ ! or simply
$ ! $ JGRAPH HYPERCUBE -P
$ ! If you really want lowercase to reprint input in expanded form:
$ ! $ JGRAPH HYPERCUBE "-p"
$ ! The resulting output file will have a ".jps" extension.
$!
$ ON ERROR THEN GOTO EXIT
$ ON CONTROL_Y THEN GOTO EXIT
$!
$L1:
$ P1 = F$SEARCH( F$PARSE( P1, ".JGR"))
$ IF P1 .NES. "" THEN GOTO L2
$ INQUIRE /LOCAL P1 "Input File : "
$ GOTO L1
$L2:
$ JPS_FILE = F$PARSE( P1,,, "NAME") + ".JPS"
$ THIS_FILE = F$ENVIRONMENT("PROCEDURE")
$ HERE = F$PARSE(THIS_FILE,,,"DEVICE",) + F$PARSE(THIS_FILE,,,"DIRECTORY",)
$ RUN_JGRAPH := $'HERE'JGRAPH
$!
$ TMP = F$VERIFY( 1)
$ RUN_JGRAPH <'p1' >'jps_file' "''P2'"
$ $status = $STATUS
$ TMP = 'F$VERIFY( TMP)
$!
$EXIT:
$ EXIT $status + 0*F$VERIFY( SAVE_VER)
