Dear all,

 

F_C_STRING is a new ISO_C_BINDI= NG module procedure in F2x that, after some inspection, seems to be of doub= tful value, and

the current specification also = has an issue.

 

First, does it really simply do= what can also be (more clearly, to my mind) written as

 

X // C_NULL_CHAR

 

or

 

TRIM(X) // C_NULL_CHAR

 

or am I missing something here?=

 

Second, it is unclear what happ= ens if C_CHAR has the value -1. One could conceivably fall back to default = character here, or some

words (similar as for C_F_STRPO= INTER) need to be added to delete the function in that case.

 

Regards

Reinhold
