Reply with quote

Maximum number a characters that can be stored in a variable in REXX is 250. But if I want to read a record which has a length more than 250 characters and process it in my REXX program, the variable will not be able to hold it.

Is there any way to handle records of more than 250 characters in REXX?

NO!

250 is the maximum length of the NAME of the variable ..

it should be very simple to read the manual or run a little REXX to find out by brute force

Code:
/* rexx*/

numeric digits 12

s = "A"

do    i = 1 to 64
   s = s || s
   say right(i,2) length(s)
end

exit


I do not have the system up right now ...
but using object rexx on my MAC the string length went up ( with a reasonable performance ) to 2**32


after that the rexx seemed to hang and I interrupted it

From REXX manual,

Quote:
There is no limit to the length of the values of variables, as long as all variables fit into the storage available.

Implementation maximum: No single request for storage can exceed the fixed
limit of 16 MB. This limit applies to the size of a variable plus any control
information. It also applies to buffers obtained to hold numeric results.

The limit on the length of symbols (variable names) is 250 characters



Hope this helps.


Thanks,
Arun
