fixing a REXX bug

Please check (execute) the program after you "fix" a bug to ensure that the output is (still) correct.   There was no bug in the REXX program you "fixed".   The output was correct with the original program. -- Gerard Schildberger (talk) 23:20, 3 March 2015 (UTC)

My bad. But when I tried to run your program as-is, I received the following message:
c:\Users\hackerg\Downloads>rexx lcsubstr.rex
10 *-* parse arg x,y,$
Error 13 running c:\Users\hackerg\Downloads\LCSubstr.rex line 10: Invalid chara
cter in program
Error 13.1: Incorrect character in program "$" ('24'X)
As it is, I assume that that must mean that there is no boundary checking in REXX. When I tried to implement it as-is in C# I got an out-of-bounds error, and by subtracting j from the length of x I corrected that error and produced the correct result when I executed the program. --Geoffhacker (talk) 07:30, 4 March 2015 (UTC)
