Re: [bascom] BASCOM AVR Passing a string by subroutine

["trbrenke" <trbrenke@educationexplorations.com>]

send the address of the string varable instead.

then let your sub read it from that memory location.

 

dim lcd_string as string * 20

 

main

  to_sub = VARPTR( lcd_string )

  call lcd_something(to_sub)

 

 

 

 

                            as word

sub lcd_something(address_string) 

  local loc_string as string

  loc_string = inp(address_string)

  for x = 1 to 18

     loc_string = loc_string + inp(address_string + x)

  next x 

 

 

end sub

Subject: [bascom] BASCOM AVR Passing a string by subroutine

 

Just curious,

 

Has anyone tried to pass a string variable in a "SUB" ?

My subroutine displays a "passed" string on an LCD display. If I keep the string length to 4 characters, it displays fine using the LCD command.

Anything longer is not displayed.

 

Declare Sub will not let me set the string length.

I tried to "dim" the string before I declared the sub with the same results.

 

Any ideas???
