|
|
Hi
I am new to REXX and while going through initial document available I came across an example for Absolute Position in PARSE which is not clear to me. Can someone help me to understand
MYSTR=" WE HAVE MET THE ENEMY, AND HE IS US. "
PARSE VAR MYSTR V1 =10 V2 V3 V4 17 V5 =25 V6 1 V7 V8
Output is something like this
V1 > " WE HAVE "
V2 > "MET"
V3 > "TH"
V4 > ""
V5 > "E ENEMY,"
V6 > " AND HE IS US. "
V7 > "WE"
V8 > "HAVE MET THE ENEMY, AND HE IS US. "
I can understand how V1, V2 got the value, but confusion is with V3 and V4,V5 value.
Can some help me how these values are assigned.
Thanks |

I did not get the same results as you. You will not get good answers if your examples are not correct.
Using '=10' will cause a break at the column, not on a word boundary.
And if you use something like '=10 v3 =18', it will cause it to include spaces within the variable. |
