Guide To Pick/Basic Programming Language

Pick/Basic is a high-level beginner’s all-purpose symbolic instruction code programming language designed mainly for the implementation of application requirements. It contains an umpteen number of statements that can be stored as subroutines or programs in any pattern. Programs that are being developed using Pick/Basic language are of editor’s choice those nest as items within a document. 

Prior to the carrying out of tasks, existing programs must be compiled well to decipher them into an object code. And all these compiled programs are piled in a document that incorporates the source code. These complied programs can now be documented as VERBS within the users dictionary.

Common Commands (VERBS):

AS	Assembler
BLOCK-PRINT	Print letters as blocks
CHARACTERS	Print ASCII character set
CHARGES	Total time logged on and CPU activity stats
COPY	Copies an item
CREATE-FILE	Creates a new dictionary & data file
CT file item	Copy an item to terminal
DTR radix #	Convert Decimal to Radix (default 16)
DUMP frameid	Binary dump of virtual disk frames
ECHO ON/OFF	Terminal echoing ON or OFF
LISTFILES	List of files
LISTPROCS	List of PROCs
LISTU	PROC showing who is on the computer
LISTVERBS	List all VERBS
LOGTO name	Change to another user
LOGOFF	Logout
MSG	Sends a message to another user.
POVF	Print OVerFlow tells how much disc is free
PRINT-ERR	Output specified error message number (ERRMSG)
RECOVER-FD	Recover editor deleted (FD) item.
RUNOFF	Output processor (like VMS runoff and UNIX nroff)
SAVE	Backup system to tape or floppy
SET-FILE	Create a synonym file called QFILE in your MD
SETUP-ASSY	Setup account for assembler (run from SYSPROG)
SLEEP	Take a nap for n seconds or until given time
SP-STATUS	Printer spooler status
T-ATT	Attach the tape drive
T-READ	Read from the tape drive
T-DET	Detach the tape drive
TABS	Display tab stops
TERM	Specifies terminal characteristics
TIME	Shows current date & time
TA-ON/OFF	Typeahead ON or OFF
WHAT	Displays system configuration
WHERE	Current information on processes
WHO	Display your account name (WHO * is for all)

In R83 and OA/RT, source code of Pick/BASIC is compiled to a tokenized object code whereas in D3, it may be "Flash'ed", optimized or compiled in the traditional way. Object code that is being generated in this pattern runs much faster than the original tokenized object code, but not as fast as that of the assembly language code of the C compiler. 

Since the onset of Flash-able source code, Pick/BASIC language is referred to as FlashBASIC.
