#BREAKPOINT Built-In Function
#BREAKPOINT Built-In Function
Use #BREAKPOINT to set or delete a _DEBUGGER breakpoint for a specific variable
level.
variable-level
is the name of an existing variable level.
state
is either a nonzero value, which sets a breakpoint for the variable level, or zero,
which deletes an existing breakpoint.
Result
#BREAKPOINT returns the previous breakpoint state of the variable level: 0 if there
was no breakpoint, -1 if there was one.
Considerations
•
A debugging breakpoint causes TACL to invoke _DEBUGGER just before invoking
a variable level having the breakpoint. Only invocation has this effect; no other
usage of the variable level (pushing, setting, and so on) causes TACL to invoke
_DEBUGGER.
•
For additional information about the TACL debugger, see the DEBUGGER
Function on page 8-51.
