EQA1491S There is no variable named character string, and if it is meant to be a built-in function, the maximum number of arguments to the character string built-in function is number, but number were specified. If it is meant to be a STORAGE alteration command, the syntax is not valid.

Explanation

A subscripted variable could not be found. Its name, however, is also that of a PL/I built-in function. If the built-in function was intended, the wrong number of arguments were present. It can be also STORAGE alteration function. If that command was intended, then invalid syntax was present.
