D.5.1.5 init_debug

Procedure from library classify.lib (see classify_lib).

Usage:

init_debug([level]); level=int

Compute:

Set the global variable @DeBug to level. The variable @DeBug is used by the function debug_log(level, list of strings) to know when to print the list of strings. init_debug() reports only changes of @DeBug.

Note:

The procedure init_debug(n); is useful as trace-mode. n may range from 0 to 10, higher values of n give more information.

Example:

LIB "classify.lib";
init_debug();
debug_log(1,"no trace information printed");
init_debug(1);
→ Debugging level change from  0  to  1
debug_log(1,"some trace information");
→ some trace information
init_debug(2);
→ Debugging level change from  1  to  2
debug_log(2,"nice for debugging scripts");
→ Debug:(2):  nice for debugging scripts
init_debug(0);
→ Debugging switched off.
