Hide lines in SCREEN
Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $ScrHide function is '''[[to be entered]]'''.

This [[Calling Sirius Mods $functions|callable]] function adjusts a <var>SCREEN</var> structure so that all fields after a specific line
number are hidden (not displayed) on subsequent <var>READ SCREEN</var> statements.
This makes it possible to build a screen that contains more lines than would fit
on all terminal models and then hide an appropriate number of lines based on
terminal model number.
The <var>$ScrHide</var> statement can also be used to provide space
for the <var>[[$ScrWide]]</var> function for Model 5 terminals.

==Syntax==
%result = $ScrHide(scr_name, line_num)


===Syntax terms===
<table class="syntaxTable">
<tr><th>%result</th>
<td>This numeric value indicates the function result.</td></tr>

<tr><th>scr_name</th>
<td>The name of the screen on which fields are to be hidden.</td></tr>

<tr><th>line_num</th>
<td>The line number of the first line on the screen to be
hidden. Fields on this line number and all subsequent lines are hidden. </td></tr>
</table>

===Status codes===
0 — No errors
1 — SCREEN does not exist or invalid screen name
2 — Invalid line number


==Examples==
<ol>
<li>This code fragment hides all lines after line 24 on screen <code>INPUT</code>:
[%rc =] $scrhide('INPUT', 24)


<li>Using <var>$ScrHide</var>, <var>$ScrWide</var> and <var>[[$ScrSize]]</var> you can expand the number and
size of 3270 screen lines available to your <var class="product">User Language</var> programs to
the maximum that will fit on the terminal type.
Here is an example technique for presenting as much information as the user's screen can contain:
SCREEN USER1
* Line 02:
PROMPT '===>' WHITE AT 2 -
INPUT COMMAND GREEN AT 7 LEN 40
* Line 03:
PROMPT LINE1 AT 2 LEN 77
* Line 04:
PROMPT LINE2 AT 2 LEN 77
...
* Line 44:
PROMPT LINE42 AT 2 LEN 77
* Line 45:
PROMPT LINE43 AT 2 LEN 77
END SCREEN
%SCR.LENGTH = 24
%SCR.WIDTH = 80
%SCR.MODEL = $VIEW('MODEL')
JUMP TO (MOD0, MOD0, MOD3, MOD4, MOD5) %SCR.MODEL
JUMP TO MOD0

MOD3: %SCR.LENGTH = 32
JUMP TO MOD0
MOD4: %SCR.LENGTH = 43
JUMP TO MOD0
MOD5: %SCR.LENGTH = 27
%SCR.WIDTH = 132
MOD0: %MAX.WIDTH = %SCR.WIDTH - 3
%X = $SCRHIDE( 'USER1' , %SCR.LENGTH )
%X = $SCRWIDE( 'USER1' )
%SCROLL.LEN = %SCR.LENGTH - 7
FOR %X FROM 1 TO %SCROLL.LEN + 1
%LINE = 'USER1:LINE' WITH %X
%X = $SCRSIZE( %LINE , %SCR.WIDTH )
END FOR
