High-Level Screen Management Intrinsic Library Reference Manual (32424-90002)
2- 8
5. You cannot call tHE HPDREAD and HPDPROMPT intrinsics directly
following a call to HPDENABLETERM. This is because Hi-Li expects
to see the HPDSEND intrinsic that sets up the form. To call
HPDREAD or HPDPROMPT in this case, call HPDSEND first.
6. The following read sequences are allowed:
a. A read call following a send and/or a prompt.
b. A read call followed by a second read call with the 'doreread'
option.
7. You cannot call HPDREAD or HPDPROMPT directly follow ing a call to
HPDPRINTFORM. This is because HPDREAD and HPDPROMPT use the form
referenced by the previous HPDSEND intrinsic.
Only one Hi-Li storage area is allocated for form information.
When HPDSEND is called, it sets up this storage area with certain
values. When HPDPRINTFORM is called, it resets these values.
Therefore, to call HPDREAD or HPDPROMPT after making an
HPDPRINTFORM call, call HPDSEND.
8. You cannot mix Hi-Li calls with VPLUS/V calls.
9. A forms file must be opened before you can use the HPDCLOSEFORMS
intrinsic to close it.
10. The terminal must be enabled before you can use the
HPDDDISABLETERM intrinsic to release it.
11. Consecutive forms file opens are not allowed. Always close the
open forms file before opening another.
12. Consecutive terminal enables are not allowed. Always disable the
enabled terminal before enabling a second one.
