Add SETSTR/INCLUDESTR for some basic code building
It seemed useful to have the ability to build up a variable containing
arbitrary text and then to be able to include that in the assembly process
like an include file. So add, undocumented for now, the following:
SETTSTR varname="string"
INCLUDESTSR "string"
"string" must be enclosed in double quotes and may contain most of the usual
escape sequences (\t, \r, etc.) as well as %(varname) to interpolate a
variable value.
To use it to create assembleable source code, you need to make sure it
creates lines (ended by either \r or \n) with appropriate whitespace in
appropriate places.
