Also - did this happen in the previous version?
Message appears as soon as the program starts - no line number shown.
Martyn pointed out that Turbo cannot compile (for QDOS, this is only possible on SMSQ/E) M/C functions that require to pass-back String values by REFerence within the parameter-list, instead of via a standard RETurn. The most common such function is the 'GET' function form TK2 which, rather than returning a String result, actually updates the passed String parameter.
So probably the use one GET command in my code is the culprit - will change it to Turbo's GET$
