#972 CBL_GC_GET_SCR_SIZE

[Eugenio Di Lorenzo]

As noted at https://sourceforge.net/p/gnucobol/discussion/help/thread/319f6cb1fd/?limit=50#dda6
at chapter 8.2.36. CBL_GET_SCR_SIZE we need to correct variable format to the following:

01  NO-OF-LINES             USAGE BINARY-CHAR UNSIGNED.
01  NO-OF-COLUMNS           USAGE BINARY-CHAR UNSIGNED.

I believe the same correction should also be made to chapter 8.2.35 CBL_GC_ SET_SCR_SIZE

Please insert also following phrase in PG.
This function will not deliver the correct results if the lines or columns exceed 255.

In the meantime, at chapter 8.2.35 CBL_GC_ SET_SCR_SIZE the underline should be moved to the right, from:

CALL "CBL_GC_SET_SCR_SIZE" USING no-of-lines, no-of-cols
~~~~                    ~~~~~

to

CALL "CBL_GC_SET_SCR_SIZE" USING no-of-lines, no-of-cols
~~~~                       ~~~~~
