These routines prompt the user on-line to the executing program for input from the terminal, and read it. The prompt is written to standard output by calling TMPRO, the input is read from standard input with TMREAD. Whether or not standard input is in fact a terminal can be detected with INTRAC (Z044); if it is not the call to TMPRO should be by-passed.
Structure:
SUBROUTINE subprograms
User Entry Names: TMINIT, TMPRO, TMREAD
Files references: standard input, standard output
Usage:
Initialize the dialogue
On some machines it is necessary to switch off buffered mode
on standard output, this is done by calling once, and before
the first call to TMPRO:
CALL TMINIT (IFINIT)
IFINIT* is reset to non-zero by TMINIT
Put the prompt to standard output
CALL TMPRO (TEXT)
TEXT is the character string to be written
Read next line from standard input
CALL TMREAD (MAXCH, CHLINE, NCH, ISTAT)
MAXCH maximum number of char. to be stored into LINE
LINE* text read, of type CHARACTER
NCH* number of characters read into LINE
ISTAT* status returned:
= 0 success
< 0 end-of-file seen
> 0 read error
