Use
The purpose of this call is to write the following string to all of the active output streams.
Notes
This SWI writes the null terminated string following this SWI in memory using OS_WriteC. It uses the value in R14 to find the string, and updates R14 to point after string.
If WrchV has not been intercepted with OS_Claim it will directly call the VDU driver which is faster, otherwise it calls OS_WriteC to write each character.
This SWI can not be conditionally executed [unless the string you wish to write out also happens to be valid ARM code for the condition failed case :-) ].
