1 :Info:  use_ep_basic:  11/08/83 use_ep_basic
 2 
 3 Syntax:  use_ep_basic
 4 
 5 Function: Set the precision of BASIC programs run under the FAST subsystem to
 6 be extended precision.  This may be used to reset the precision from the
 7 single precision mode.
 8 
 9 
10 Notes: Single and extended precision programs should not be run at the same
11 time because the numeric arguments and numeric files are not compatible.  The
12 convert_numeric_file command is available for converting numeric files from
13 single to extended and vice versa.
14 
15 The precision state is saved when the FAST subsystem is entered, and is
16 reset to the saved state when exited. Thus, use of the use_sp_basic and
17 use_ep_basic commands will not affect the BASIC environment outside of the
18 FAST subsystem.

21 A new statement type has been added to provide a means of dynamically
22 controlling the number of digits in a numeric value to be printed as output.
23 Its syntax is:
24    setdigits formula
25 
26 The value expressed by formula is truncated to its integer value, and
27 represents the number of digits to be printed by all future PRINT statements
28 until another SETDIGITS statement is executed, or until the end of program
29 execution.  The value can be 1 through 19.  This statement applies only to
30 nonintegers.  The tab spacing is adjusted to accomodate the current number
31 length.  However, the spacing will never be less than the default.

34 :Info: use_sp_basic:  11/08/83 use_sp_basic
35 
36 Syntax:  use_sp_basic
37 
38 Function: Set the precision of BASIC programs run under the FAST subsystem to
39 be single precision. This is the default precision, and may be used to reset
40 the precision from the extended mode.
41 
42 
43 Notes: To get extended precision, invoke the use_ep_basic command with no
44 arguments.  Extended precision stays on until the use_sp_basic command is
45 issued.
46 
47 Single and extended precision programs should not be run at the same time
48 because the numeric arguments and numeric files are not compatible.  The
49 convert_numeric_file command is available for converting numeric files from
50 single to extended and vice versa.
51 
52 The precision state is saved when the FAST subsystem is entered, and is
53 reset to the saved state when exited. Thus, use of the use_sp_basic and
54 use_ep_basic commands will not affect the BASIC environment outside of the
55 FAST subsystem.

63 The value expressed by formula is truncated to its integer value, and

66 execution.  The value can be 1 through 19.  This statement applies only to
67 nonintegers.  The tab spacing is adjusted to accomodate the current number
68 length.  However, the spacing will never be less than the default.
