FORDDT.HLP -- HELP file for FORDDT-20 version 10 January 1985
---------------
Compilation, loading and execution
To start FORDDT:
@DEBUG filename.ext/DEBUG
---------------
FORDDT commands:
ACCEPT VAER/M CVE or F format spec
CHARACTER A(CVE:CVE,CVE:CVE,...) or A/REMOVE [Character array]
CONTINUE CVE
DDT
DIMENSION A(CVE:CVE,CVE:CVE,...) or A/REMOVE [Single precision
array]
DOUBLE A(CVE:CVE,CVE:CVE,...) or A/REMOVE [Double precision
array]
GOTO SL or (contents of) VE
GROUP number 'TYPE' command list /G,/G,/G.....
HELP
LOCATE VASLF
MODE M,M,...
NEXT CVE
OPEN program unit name
PAUSE SLY AFTER CVE TYPING G
SLY IF CVE .relop. CVE TYPING G
REMOVE SLY
START
STOP /RETURN
STRACE
TYPE /M VAER/M , F , G , ...
WHAT
---------------
FORDDT command parameter formats:
note: CVE means constant/variable/array element
constant (C):= 5 , 5. , 5.E2 , 5.D3 , (1.0,-1) , "77 , /ABC/ ,
'abc'
variable (V):= name
array (A):= name
array element (E):= name(CVE:CVE,CVE:CVE,...)
array range (R):= E-E
statement label (S):= 10
source line # (L):= #13
format # (F):= 101
format spec := ( FORMAT descriptor list ) ie. (F10.3,I5,...)
routine entry (Y):= name
mode (M):= /A ASCII (left-justified) /ABC/
/B BIG (display both words of a two-word
variable; use only with
/A, /D, /R, /X.
/B can also be used to display
character strings longer the the
default, e.g. 256 characters.)
/C CHARACTER 'ABC'
/D DOUBLE-PRECISION 123.4567890
/F REAL 123.45678
/I INTEGER 123
/L LOGICAL .TRUE.
/O OCTAL 12345678
/R RASCII (right-justified) \ABC\
/S SYMBOLIC PSI(2,4)
/X COMPLEX (1.25,-78.E+9)
FORDDT looks at the first character of the
switch only, and disregards the rest.
Example: /REAL would be interpreted as /R, and
the mode would be interpreted as RASCII.
group reference (G):= /groupnumber ( 1<= G <=8 )
---------------
Comments can be included in command lines by use of an exclamation
point. Example:
>> PAUSE 10 !This is a comment
