Options Name Purpose
+ HANDLE FindPersistentProcedure (character) Searches for the first instance of a persistent procedure with the given name

PUBLIC HANDLE FindPersistentProcedure (character)
Purpose: Searches for the first instance of a persistent procedure with the
given name
Notes:

Parameters:
pcFileName CHARACTER
The file name of the persistent procedure to search for
Returns HANDLE
The handle of the persistent procedure instance or ? when no instance is found
Top

PUBLIC HANDLE FindPersistentProcedure (character, logical)
Purpose: Searches for the first instance of a persistent procedure with the
given name, if not found, supports starting the persistent procedure when not found
Notes:

Parameters:
pcFileName CHARACTER
The file name of the persistent procedure to search for
plStart LOGICAL
Start the persistent procedure or not
Returns HANDLE
The handle of the persistent procedure instance or ? when no instance is found
Top

PUBLIC LOGICAL HasEntry (handle, character)
Purpose: Returns true if the procedure or it's super-procedures contains the
given entry (internal procedures or user defined functions) and thus
the given entry is callable (RUN or DYNAMIC-FUNCTION).
Notes:

Parameters:
phProcedure HANDLE
The handle of the persistent procedure
pcEntry CHARACTER
The name of an internal procedure or user defined function
Returns LOGICAL
TRUE when an entry is found, else FALSE
Top

PUBLIC LOGICAL HasEntry (handle, character, character)
Purpose: Returns true if the procedure or it's super-procedures contains the
given entry (internal procedures or user defined functions) and thus
the given entry is callable (RUN or DYNAMIC-FUNCTION).
Notes:

Parameters:
phProcedure HANDLE
The handle of the persistent procedure
pcEntry CHARACTER
The name of an internal procedure or user defined function
pcType CHARACTER
The entry type, PROCEDURE or FUNCTION
Returns LOGICAL
TRUE when an entry is found, else FALSE
Top

PUBLIC LOGICAL HasEntry (handle, character, EntryTypeEnum)
Purpose: Returns true if the procedure or it's super-procedures contains the
given entry (internal procedures or user defined functions) and thus
the given entry is callable (RUN or DYNAMIC-FUNCTION).

Parameters:
phProcedure HANDLE
The handle of the persistent procedure
pcEntry CHARACTER
The name of an internal procedure or user defined function
poType Consultingwerk.EntryTypeEnum
The entry type as an EntryTypeEnum member
Returns LOGICAL
TRUE when an entry is found, else FALSE
Top

PUBLIC LOGICAL HasEntryMatching (handle, character)
Purpose: Returns true if the procedure or it's super-procedures contains the
given entry (internal procedures or user defined functions) and thus
the given entry is callable (RUN or DYNAMIC-FUNCTION).
Notes: Uses MATCHES to compare pcEntry to the name of the internal entries

Parameters:
phProcedure HANDLE
