RE: [sqr-users] RAT in sqr - search char string for first pos of charstarting from the right?

Paul,

STRRCHR will return a 0 if the character is not found otherwise the
offset into the string.

Begin-Report
 Let $String = 'c:\dir1\dir2\file.txt'
 Do STRRCHR($String, '\', #Offset)
 Show #Offset
End-Report

Begin-Procedure STRRCHR($String, $Char, :#Offset)
 Let #OffSet = Instr(Edit($String, 'R'), $Char, 0)
 If (#Offset)
  Let #Offset = Length($String)-#Offset+1
 End-If
End-Procedure 

Peter

char starting from the right?


Hi All,

How do I search a char string for the first occurance of a character
going
from right to left?

Example

c:\dir1\dir2\file.txt

How do I find the position of the THIRD \ (answer would be 12).

Thanks, Paul
