RE: [WDSCI-L] CL Formatting, was WDSc workstation requirements

["SamL" <lennon_s_j@xxxxxxxxxxx>]

Yes, it aligns DCLs, like this:
   DCL VAR(&BGNCOL)     TYPE(*DEC)  LEN(2 0)
   DCL VAR(&CVTCASE)    TYPE(*CHAR) LEN(6)
   DCL VAR(&INDCOL)     TYPE(*DEC)  LEN(1 0)
   DCL VAR(&INDCONT)    TYPE(*DEC)  LEN(1 0)
Also, at runtime it allows you to specify the number of columns to indent
from the left, at each break level and on each continuation line.  The only
thing it doesn't do well, IMHO, is comment lines.  But since I usually put
them last and it has an option to leave comment lines alone, that doesn't
bother me much anyway.

I find it extremely useful and often use it when researching code written by
others.
