I guess you mean the error message
"resultant symbol exceeds 100 characters"

In include src/glpmpl.h you can find the following definition:

#define MAX_LENGTH 100
/* maximal length of any symbolic value (this includes symbolic names,
   numeric and string literals, and all symbolic values that may appear
   during the evaluation phase) */

Try to avoid concatenations in the printf statement.
Eg. replace
printf "abc" & "def";
by
printf "%s%s", "abc", "def";
or by
printf "abc"; printf "def";

Best regards

Xypron
