OpenTmpScriptFile - open a temporary script file to contain program
script input
SYNOPSIS
OpenTmpScriptFilescript_filename channel [mode]
DESCRIPTION
Open a temporary file to be used as the script input to a program. The
file name, generated automatically, is
projectname_jobnumber_filenumber_com.tmp,
and the name is returned in script_filename. The file is opened
and the channel id is returned in channel. By default the file is
opened in w+ mode, which is write enabled and appending
to any existing file of the same name (see Tcl documentation on
file open) but this can be overridden by an optional
mode.
HINTS
For all but the very simplest scripts, it is easier to generate the script
using CreateComScript and a template file. Use OpenTmpScriptFile
with WriteTmpFile to write a file explicitly, and remember to close
the file with 'CloseFile$channel'.
See the file $CCP4I_top/script/import.script for an example of the use
of OpenTmpScriptFile.
