Debug

Commande yes debug activates debug mode, interpreter is invoked before executing each instruction, it is then possible to consult or change any variables, execute any function and, more generally, execut any commande..

Continuation

         1) continuation Key can be changed in file enva.h (escape ASCII code 27 by default).
         2) Edited at programme launching.
         3) Command debug ascii:
debug ascii: return the key continuation (27=escape by default).
debug ascii("c"): set c key to continuation key.
Examples:
$(debug) ascii: gives 27.
debug ascii("`"): changes the key continuation into grave accent.

Pratically

         Invokes commande yes debug.
quitte debug mode with no debug.
         Le propmtbecomes DEBUG>
         Press key continuation then ENTER
         Prompt becomes again ?
         Write a command (for example a function to debug)
         The name of the function, the number of the line to drebug and tej text le text of this line are edited
         The interpreter waits: we can execute any command
         The continuation key followed by ENTER continue.

debugger commands

Avancer

         1) The continuation key foillowed by ENTER continue
         2) no debug;, followed by the continuation key and ENTER abandonnes the debugger mode
         3) GO executes until next break

Points d´arrêt

         1) STOP num sets a break point line number num of the function
         2) STOP "toto" sets a break point to function toto
         3) STOP "toto",num stes a break point at line number num of function toto
         4) edit STOP edits the STOPs
         5) rem STOP num deletes STOP num
         6) rem STOP "toto" deletes STOP "toto"
         7) rem STOP "toto",num deletes STOP "toto",num
         8) ini STOP deletes all of the STOPs

Lister

         1) LIST edites 20 lines after the instruction
         2) LIST n edites line number n of function
         3) LIST n1,n2 edites lines lignes n1 to n2 of function
         4) LIST "toto" edites function toto
         5) LIST "toto",n edites line number n of function toto
         6) LIST "toto",n1,n2 edites lines n1 to n2 of function toto

Debugger sous windows (Visual C++)

Launche programme with debug option (see la doc du VisualC++).
sets a break to line if(i) after line

i = 0;	/* Break debug */

of function inita of file inita.c, then assignes 1 to variable i.
messages Rentrer une suite d'options, terminer par .
enter options one after other
enter . (point)

UNDER IMPLEMENTATION

Debugger sous dbx(UNIX)
         Lancer le programme sous dbx:
         dbx anyflo
         >run
         Exécuter des fonctions
         ^C interromp le traîtement
         >assign Debug=1
         >c
         À l´exécution d´une commande l´interpreteur a la main avec le prompt:
         DEBUG>
         N´importe quelle line de commandes peut être exécutée
