Reading tab-delimited files

How can I read columns with information from a tab-delimitid file with GWBasic? With MID$ in some textfiles columns shift when a previous column gets wider, although one does not see this when one opens the textfile with for example EDIT.

I suspect the problem is that some of the column data strings are longer than the default tab width. I don't remember there being a way to change GWBasic's tab width so you will have to change it yourself in code:
100 DEFINT A-Z 110 colwidth = 10 120 OPEN "filename" FOR INPUT AS #1 140 WHILE NOT EOF(1) 150 LINE INPUT #1, l$ 160 colpos = 1 170 FOR i = 1 TO LEN(l$) 180 c$ = MID$(l$, i, 1) 190 IF c$ <> CHR$(9) THEN PRINT c$; : NEXT i 200 colpos = colpos + colwidth 210 LOCATE CSRLIN, colpos 220 NEXT i 230 PRINT 240 WEND 250 CLOSE #1
You will have to straighten out the line wraps. Change the columw width at line 110 until it displays correctly.
If this doesn't do it for you it should give you some other ideas to try. Good luck!
