Syntax

screen_no = PUSH_SCR()

Purpose

Save the current screen to a SCREENS file. Each user has exclusive use of a
uniquely named file, SCRN1.FIL, SCRN2.FIL, etc. The first call to PUSH_SCR()
creates the file. SIGN_OFF() calls SCRAPFILES() to delete it on exit.
If you do not exit with SIGN_OFF() or QUITPROG(), you must call SCRAPFILES().

Arguments

     None.

Setup

None required.

Example

     screen_no = PUSH_SCR()
     MY_SCREEN()                  /* a function you write */
     POP_SCR( screen_no )

Returns

The record number of the saved screen.

Side Effects

Will overwrite the next 4000-byte record in SCREENS, or add 4000 bytes at
EOF.

Artful Calls

None.
