FNpsinput function
Post by Wendell on Mar 23rd, 2014, 06:07am

*font Segoe print,11,B
PRINT TAB(32,10) "First Name: "

INPUT TAB(42,10)a$

PRINT TAB(30,11) " TENMADS : ";

INPUT TAB(45,21)b$




What is the format to correct the input statment.. for the above program will not, backspace correctly ?

I have updated your code hoping that this is what you meant -

Code:
     *font Segoe print,11,B

      INPUTTAB(32,10)"First Name: ";a$

      INPUTTAB(32,12)"TENMADS ";b$


If you are querying on how to use the INPUT Keyword correctly then these two Wiki links may help and then is always the 'Help Topics' and 'Tutorial' -

You answered the question in your subject line: use the FNpsinput routine. However that routine, unmodified, does not work well with italic characters so in the code below I've added a SYS "SetBkMode" to resolve the issue:

Code:
      SYS "SetBkMode", @memhdc%, 1
      *font Segoe Print,11,B
      PRINT TAB(32,10) "First Name: ";
      a$ = FNpsinput(42,10,"")
      PRINT TAB(32,11) "TENMADS : ";
      b$ = FNpsinput(45,11,"")

As the previous respondent noted you could incorporate the prompt string into the function call, but in so doing it's more difficult to position the cursor exactly where you want it, so I don't necessarily recommend it:

Code:
      SYS "SetBkMode", @memhdc%, 1
      *font Segoe Print,11,B
      a$ = FNpsinput(32,10,"First Name: ")
      b$ = FNpsinput(32,12,"TENMADS : ")

SYS "SetBkMode", @memhdc%, 1
*font Segoe Print,11,B
PRINT TAB(32,10) "First Name: ";
a$ = FNpsinput(42,10,"")
PRINT TAB(32,11) "TENMADS : ";
b$ = FNpsinput(45,11,"")



IF you run this ... a$ = FNpsinput(42,10,""),,,, no such FN/PROC error mess

I hardly dare ask this, but have you actually copied-and-pasted FNpsinput into your program?? rolleyes

You will save yourself a great deal of time and frustration if you develop a better understanding of the fundamentals of BBC BASIC. Once again I would strongly urge you to work through the Beginners' Tutorial, which you can access from the Help menu (the second item after Help Topics). Please note that the Tutorial is not the same thing as the BB4W Help documentation - one or two of your previous comments make me wonder whether you have muddled them up.
