2.11 Calling subroutine with path specification and parameters (PCALL)

2.11 Calling subroutine with path specification and parameters (PCALL)
2.11
Function
With PCALL you can call subroutines with the absolute path and parameter transfer.
Programming
PCALL <path/program_name>(parameter 1, ..., parameter n)
Parameters
PCALL
<path_name>
Parameters 1 to n
Example
PCALL/_N_WKS_DIR/_N_SHAFT_WPD/SHAFT(parameter1, parameter2, ...)

Extend search path for subroutine calls with CALLPATH

2.12
Function
The CALLPATH command is used to extend the search path for subroutine calls. That
allows you to call subroutines from a non-selected workpiece directory without specifying the
complete absolute path name of the subroutine.
Search path extension precedes the user cycle entry (_N_CUS-DIR).
Deselection of the search path extension
The search path extension is deselected with the following events:
• CALLPATH with empty string
• CALLPATH without parameters
• End of parts program
• Reset

Keyword for subroutine call with absolute path name
Absolute path name beginning with "/", including subroutine
names
If no absolute path name is specified, PCALL behaves like a
standard subroutine call with a program identifier.
The program identifier is written without the leading _N_ and
without an extension.
If you want the program name to be programmed with the
leading _N_ and the extension, you must declare it explicitly
with the leading _N_ and the extension as Extern.
Current parameters in accordance with the PROC statement of
the subroutine.
