String System Variable

String, operating system's directory delimiter

Description

The DLM variable contains the operating system's directory delimiter (e.g. "/"... for UNIX, "\"... for Windows).

Example:

On a Windows PC:

?dlm
\

Helpful Tip:
Use SEP=DLM when reading directories (e.g. in list boxes) to have PxPlus append the operating system delimiter to sub-directory names.

Example

The following is a Tree View list box example:

     list_box 10,@(5,5,25,10),opt="e|",fmt="!diskette|!File|!File_open",sep=dlm
     F=1,D$="."
NXTDIR:
     open (F)D$
NXTFILE:
     read (F,end=ENDDIR)F$
     if F$(1,1)="." \
             then goto NXTFILE
     if mid(F$,-1)<>dlm \
             then list_box load 10,0,pth(F)+dlm+F$;
                     goto NXTFILE
     D$=pth(F)+dlm+F$
     F++
     goto NXTDIR
ENDDIR:
     close (F)
     F--
     if F>0 \
             then goto NXTFILE
     escape
