-xrm command-line option
The -xrm command-line option allows an individual resource (setting) to be changed.
In x3270, this is a standard Xt command-line option.
Syntax
The syntax of an -xrm option is identical to a single line of a session file -- excepting, of course, comments lines and multi-line definitions.
Examples
Define the blankFill resource to true.
-xrm "*blankFill: true"
Define blankFill for wc3270 to true.
-xrm "wc3270.blankFill: true"
Define a wc3270 traceDir resource. Note that backslashes in Windows pathnames must be doubled.
-xrm "wc3270.traceDir: C:\\Users\\Bob\\Trace Files"
