The maximum length for a string constant in OS/2 REXX is 250. To use strings
longer than 250 chars, split them into pieces less than 250 chars and concatenate
them in a variable. (There's no limitation for the length of the contents
of a variable in OS/2 REXX.)
Example:
myConstant =, "This is a really long string constant. " || , "Well, because it is to long for a constant in OS/2 REXX " || , "We split it into smaller pieces and concatenate them " || , "with the operator || to a big string and save the " || , "result in a variable. This is possible, because there " || , "is no limit for the length of a variable in REXX. "
