aryTrace

Set the internal ARY_ system error-tracing flag

Description:

This function sets an internal flag in the ARY_ system which enables or disables error-tracing messages. If this flag is set non-zero, then any error occurring within the ARY_ system will be accompanied by error messages indicating which internal routines have exited prematurely as a result. If the flag is set to zero, this internal diagnostic information will not appear and only standard error messages will be produced.

Invocation

char aryTrace( char newflg )

Notes:

Parameters :

newflg
The new value to be set for the error-tracing flag. If a negative value is supplied, the existing value is left unchanged.
