Combine data from different columns in file using ISPF command.

Postby Rabindra Kumar » Mon Oct 03, 2016 3:03 pm

Hi,

Suppose in a PS file, I have data in columns 5-20, 50-60 and in between there are spaces. How can I bring the data from columns 50-60 to 21-31? All the records, across, the columns are of same length. Do we have any ISPF command for this? Please share the command if there is any.

Hi,

I think you can use SORT too for this. SQUEEZ fucntion should work for your case.

not natively ...
the approach to be used depends on the size of the data being edited,
sort will be the preferred way for large amount of data

but ...

here is a sample rexx edit macro which will MOVE and swap colums
save it two times in a library in the sysproc or sysexec concatenation
one time with a name like MOVECOLS ... anything You like
the second time with a name like SWAPCOLS ... anything You like as long as it contains the string SWAP

Code: Select all

TESTED AND WORKING
but ... remember UNDO is Your friend

it must be invoked as <macroname> FromColumn,FromLength,ToColumn
for the swap the From and the To columns meaning is clear
for a move its a bit more difficult to explain
the from is clear ...
the to/dest is a bit murky , the macro will shift things starting from that column
movecols xx,1,1
will start shifting from column 1 an makes things look as data inserted before that column
the look is natural for a move left, not the same for a move right
the column used is the one before the move, and after that everything will be shifted left
just pay attention in not being confused by the look of the data after using the macro

Simply?

Code: Select all

C " " "" 21 59 ALL

Or set the left bound at column 21 and do a block shift left("((/((" of 39 columns. Remember to reset the bounds afterwards.

I suggest you take the time to read about all the primary and line commands via the tutorial and manual and practice with them.
