Retain Leading space

Hi,

Iam trying to selecta part of a string using SUBSTR function. This works fine if the string has no leding spaces. If the string has leading spaces, its not working as expected. Can any one help me in retaining the leading spaces while using substr.

My input (variable name - ws-xyz):

Could you post the trace output within code tags?

First of all, these:

ws-xyz
ws-new-data

are invalid variable names in REXX. Adjusting for that:

ws_new_data = Substr(ws_xyz,3,2)
Say "'"ws_new_data"'"

I get:

'34'
'45'
'47'
'47'

in my output.

You have not shown how the values are assigned to the variable.

even though the TS has not returned:
1. REXX is pretty tight. i have not found (in 20 years) any problem
other than my ability to understand the manual.

2. if you think something is not working 'as expected'.
do a little debugging.

use SAY LENGTH(variable)
use SAY variable

use TRACE. I find ?R to be most helpful.

Nic's suggession of using > and < is valuable for COBOL displays also. Leading or trailing unprintable characters are spotted easily this way.
