TRDEF

Description The TRDEF command changes the length of traces A, B, or C, or creates new trace arrays, called user-de￿ned traces, for data storage or manipulation.

After a user-de￿ned trace is created, it can be used wherever user-de￿ned trace appears in the syntax diagrams.

Memory is reserved to contain up to 2048 elements of trace information (from 1 to 2048) for each of the prede￿ned traces A, B, and C. This memory is always protected and is separate from internal memory where user-de￿ned traces, variables, functions, etc., are stored. TRDEF stores user-de￿ned traces in internal memory provided there is su￿cient room. Use DISPOSE or PURGE to delete user-de￿ned traces from internal memory. If traces A, B, and C have di￿erent lengths, the active trace with the shortest length is used for the speci￿ed span. The shorter trace accepts data until ￿lled.
