diff lwasm/instab.c @ 519:724bcc4508bc

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.
